The Gujarat Anti Terrorist Squad (ATS) has arrested a 44-year-old man, suspected to be one of the conspirators of the 2002 terror attack on American Centre in Kolkata. Following a tip-off, ATS officials nabbed Hasan Imam on Saturday from his residence in Aurangabad in Bihar and brought him to Gujarat on Sunday.

An ATS release said Imam was a member of the banned terror outfit Harkat-ul-Jihadi-e-Islam (HuJI) as well as `Asif Raza Commando Force' formed by Aftab Ansari. 

Ansari was involved in the kidnapping of two Rajkot-based jewellers in November 2000, wherein a ransom of Rs 1.5 crore was paid and the money was allegedly used to fund terror activities through a network of terror groups, said the ATS.

Ansari was arrested by CBI in February 2002 upon his deportation from Dubai. He was the key accused in the terror attack on American Centre in Kolkata.

Imam allegedly worked closely with Ansari and the terror outfit Jaish-e-Mohammad to carry out the attack on the American Center in the wee hours of January 22, 2002. Four policemen were killed in the attack. 

ATS said Imam was actively involved in the conspiracy. He arranged the motorcycle used by terrorists and also provided shelter to the other accused. Later, he changed his name to Arif and settled down in Aurangabad, said the release.
