The recent arrests in Malaysia confirm that radicalisation within the Bangladeshi diaspora is a significant and evolving threat. This problem stems from socioeconomic factors, homeland instability, and online recruitment. A transparent, collaborative, and multi-faceted P/CVE (Preventing and Countering Violent Extremism) approach is essential to mitigate the risk.

COMMENTARY

Malaysian authorities recently arrested 36 Bangladeshi citizens in Selangor and Johor for their involvement in a radical militant movement promoting Islamic State (IS) ideology. Home Minister Datuk Seri Saifuddin Nasution Ismail reported that these individuals were forming recruitment cells, fundraising for terrorism, and plotting to overthrow the Bangladesh government.

Notably, the network, as detailed by police, raised funds using international fund transfer services and e-wallets, directing money to the IS group in Syria and Bangladesh. This method highlights a growing trend in terrorist financing, leveraging the speed, lower costs, and often less stringent oversight of digital platforms and cross-border money movement to facilitate illicit financial flows globally.

Of those arrested, five have been charged with terrorism-related offences, 15 face deportation, and 16 remain under investigation, with the police anticipating further arrests. Malaysian authorities estimate that 100 to 150 individuals are suspected to be involved in this network, demonstrating the scale of the threat they are actively dismantling.

These arrests are a stark reminder that the threat of extremism continues to cast a long shadow, not just within Bangladesh’s national borders but also across diaspora communities. The arrest of the 36 nationals is not an isolated incident. There have been previous cases of radicalisation of Bangladeshis in Malaysia.

In May 2019, a 28-year-old Bangladeshi mechanic was arrested in Kuala Kedah; he had possessed the necessary chemicals and expertise to produce improvised explosive devices (IEDs). Earlier in January 2017, two Bangladeshi salesmen, aged 27 and 28, were arrested in Kuala Lumpur, reportedly for having ties with suspected IS militants in Bangladesh and for planning to join a terror cell in the southern Philippines.

Singapore, among other nations, has also experienced similar cases in the past, notably in 2015, 2016, and 2020, highlighting a recurring pattern of Bangladeshi diaspora members being targeted and recruited by terrorist networks, including the Islamic State.

Background: Criminal justice agencies are well positioned to help prevent the radicalisation of individuals and groups, stop those radicalised from engaging in violence, and reduce the likelihood of terrorist attacks. This Evidence and Gap Map (EGM) presents the existing evidence and gaps in the evaluation research. Objectives: To identify the existing evidence that considers the effectiveness of criminal justice interventions in preventing radicalisation, violent extremism and terrorism. Search Methods: We conducted a comprehensive search of the academic and grey literature to locate relevant studies for the EGM. Our search locations included the Global Policing Database (GPD), eight electronic platforms encompassing over 20 academic databases, five trial registries and over 30 government and non‐ government websites. The systematic search was carried out between 8 June 2022 and 1 August 2022. Selection Criteria: We captured criminal justice interventions published between January 2002 and December 2021 that aimed to prevent radicalisation, violent extremism, and/or terrorism. Criminal justice agencies were broadly defined to include police, courts, and corrections (both custodial and community). Eligible populations included criminal justice practitioners, places, communities or family members, victims, or individuals/groups who are radicalised or at risk of becoming radicalised. Our map includes systematic reviews, randomised controlled trials, and strong quasi‐experimental studies. We placed no limits on study outcomes, language, or geographic location. Data Collection and Analysis: Our screening approach differed slightly for the different sources, but all documents were assessed in the systematic review software program DistillerSR on the same final eligibility criteria. Once included, we extracted information from studies using a standardised form that allowed us to collect key data for our EGM. Eligible systematic reviews were assessed for risk of bias using the AMSTAR 2 critical appraisal tool. Main Results: The systematic search identified 63,763 unique records. After screening, there were 70 studies eligible for the EGM (from 71 documents), of which two were systematic reviews (assessed as moderate quality), 16 were randomised controlled trials, and 52 were strong quasi‐experimental studies. The majority of studies (n = 58) reported on policing interventions. Limited evidence was found related to courts or corrections interventions. The impact of these interventions was measured by a wide variety of outcomes (n = 50). These measures were thematically grouped under nine broad categories including (1) terrorism, (2) extremism or radicalisation, (3) non‐terror related crime and recidivism, (4) citizen perceptions/intentions toward the criminal justice system and government, (5) psychosocial, (6) criminal justice practitioner behaviours/attitudes/ beliefs, (7) racially targeted criminal justice practices, (8) investigation efficacy, and (9) organisational factors. The most commonly assessed outcomes included measures of terrorism, investigation efficacy, and organisational factors. Very limited research assessed intervention effectiveness against measures of extremism and/or radicalisation. Authors’ Conclusions: Conducting high‐quality evaluation research on rare and hidden problems presents a challenge for criminal justice research. The map reveals a number of significant gaps in studies evaluating criminal justice responses to terrorism and radicalisation. We conclude that future research should focus attention on studies that consolidate sound measurement of terrorism‐related outcomes to better capture the potential benefits and harms of counter‐terrorism programs, policies and practices which involve criminal justice agencies.

The increasing involvement of women in terrorism challenges traditional perceptions and necessitates a shift in counterterrorism strategies. Recent cases in Singapore illustrate how women are radicalised through online propaganda, familial influence, and ideological indoctrination, leading to their participation in extremist activities. Addressing this evolving threat demands gender-sensitive prevention and rehabilitation efforts, community engagement, digital counterterrorism, and tailored intervention programmes to counter radicalisation at its roots. COMMENTARY The recent detention of a 15-year-old self-radicalised female student in Singapore highlights the growing vulnerability of young individuals, especially women, to extremist influences online. Her case, the first involving a female minor under the Internal Security Act (ISA), signals an alarming shift in radicalisation trends, where even adolescents are being drawn to violent ideologies. This underscores the urgency of addressing radicalisation at its early stages, particularly in digital spaces where extremist propaganda thrives. Just months earlier, the case of a 56-year-old radicalised housewife demonstrated that women are no longer confined to passive roles in extremist networks. These developments challenge traditional assumptions about gender and radicalisation, reinforcing the need for targeted intervention efforts across different demographic groups.

In many cases, women were often involved as facilitators of terrorism, providing logistical support, acting as recruiters, or serving as symbols of ideological purity. However, recent trends show a growing number of women assuming leadership roles, engaging in combat, and even carrying out suicide attacks. Several factors drive this shift, including ideological indoctrination, social and economic disenfranchisement, and extremist organisations' strategic exploitation of gender norms. Terrorist groups such as ISIS, Boko Haram, and Al-Qaeda have actively sought to recruit women, recognising their potential to evade security measures and access targets that male operatives might struggle to reach. Extremist groups have used women as suicide bombers, assassins, and enforcers of their doctrine. In some instances, they have also taken on prominent roles in radicalisation efforts, using online platforms to spread extremist propaganda and recruit new members.

How does the internet affect the radicalisation of extreme-right lone actor terrorists? In the absence of an established theoretical model, this article identifies six mechanisms seen as particularly relevant for explaining online radicalisation. Having first reviewed a larger set of relevant lone actor terrorists, the study traces the mechanisms in three selected cases where the internet was reportedly used extensively during radicalisation. The findingsshow that the internet primarily facilitated radicalisation through information provision, as well as amplifying group polarisation and legitimising extreme ideology and violence through echoing.In all three cases, radicalisation was also affected considerably byoffline push-factors that through their presence made extreme online messages more impactful. The results challenge the view that offline interaction is necessary for radicalisation to occur but also the view that online influence itself is sufficient
