Moideen was arrested in a crackdown by NIA with the help of central security agencies and other state police, foiling designs of IS operatives to target few judges of Kerala and foreign tourists visiting the coastal state. The accused, radicalised and recruited in IS through social media platforms, had left India for Istanbul from Chennai in April last year on the pretext of performing ‘Umrah’, official sources said. After reaching Istanbul, he crossed over along with other people from Pakistan and Afghanistan to Iraq.
