Kerala police have arrested Roshidul Islam, an Assam man residing in Kerala for two years, for allegedly spreading extremist ideology online. Investigators claim he shared content promoting religious hatred and communicated with individuals outside India. He is also accused of attempting to procure AK-47 rifles from Pakistan. This arrest occurs as Assam police investigate a structured extremist ecosystem with transnational links, involving groups like JMB and IMK, which use digital platforms for indoctrination and recruitment.
