The fugitive chief recruiter for the Islamic State (IS) in the Indian subcontinent, Mohammed Shafi Armar, has been recruiting youths from Bangladesh, India and Sri Lanka.
He has been using Facebook and other personal messenger services to contact, brainwash and recruit youths from the three countries, reports NDTV.
Armar, a native of Bhatkal of Karnataka, has been named a 'Specially Designated Global Terrorist' by the US on Thursday.
The US State Treasury Department, in a statement, said the IS recruiter had cultivated a group of dozens of IS sympathisers who are involved in terrorist activities across India.
An Interpol Red Corner notice is also pending against the 30-year-old man.
Armar has many aliases like 'Chhote Maula', 'Anjan Bhai' and 'Yousuf al-Hindi'.
Armar was said to have left for Pakistan along with his elder brother after the crackdown on Indian Mujahideen cadres. After a fight with Bhatkal brothers, Armar is believed to have created jihadist organisation Ansar ul Tawhid, which later pledged its loyalty to the IS.
An Indian intelligence agency had filed charge-sheet against him for allegedly conspiring to carry out terror strikes in the Indian capital and also in Haridwar.
His links to the IS were also the highlight of the interrogation of Yasin Bhatkal, who was arrested near the Nepal border in 2013.
Armar first came on the radar of investigation agencies when the National Investigation Agency (NIA) was probing suspected IS cadres in Ratlam of Madhya Pradesh.
During the interrogation of alleged IS operatives, it emerged that Armar was motivating and radicalizing Muslim youths in India. He was said to have been recruiting youths for the Jund ul Khalifa-e-Hind through online radicalisation.
When contacted by the Dhaka Tribune, Counter Terrorism and Transnational Crime (CTTC) Chief Monirul Islam said that they had not recovered any information from detained militants regarding such a recruiter operating in Bangladesh.
RAB Legal and Media Wing Director Mufti Mahmud Khan echoed the CTTC chief's remarks on the matter.
