Bangalore: Police have arrested an Indian Mujahideen operative for his alleged involvement in the Chinnaswamy cricket stadium blasts case of April 2010 in which 15 people had got injured, police said here on Thursday.

Kamal Hassan alias Bilal, 24, a native of Bihar was arrested on April 10 in Kolkata during a manhunt to apprehend blast mastermind Yasin Bhatkal, City Police Commissioner Jyothiprakash Mirji said.

Hassan was brought to Bangalore and produced before the jurisdictional magistrate which sent him to police custody, Mirji added.

Two low-intensity explosions near a packed Chinnaswamy cricket stadium less than an hour before an IPL match left 15 persons, including five security men injured.

Hassan is a member of Indian Mujahideen’s Bihar cell and a close associate of Bhatkal who is in charge of IM's urban operations in India.

He was part of the conspiracy hatched in Bihar and Delhi in 2009 of which the Chinnaswamy Stadium blasts on April 17, 2010, was a part, the Commissioner said.

 Hassan was indoctrinated to Jihadi activities by Bhatkal and tasked with looking for hideouts in Bihar and Delhi for all IM operatives involved in the stadium blasts and the terror attack at Jama Masjid in Delhi on Sept 19 2010, he said.

 Being an expert in preparing ammunition/cartridges used in firearms, he worked in the weapons factory of Bhatkal's father-in-law in Delhi on his instructions.

Hassan's movement, along with that of Bhatkal, was noticed in Bihar, Kolkata, Nepal, Maharastra, Mumbai, Uttar Pradesh, Delhi and other places. Efforts are on to apprehend Bhatkal, Mirji said.
