An investigating officer told rediff.com that they picked up Sameer Sadiq, a SIMI [Images] activist from the Gurapanapalya area in Bangalore, on Tuesday.

With this arrest, the police say it is becoming clear that SIMI was behind the blasts in Bangalore and were using the name of Indian Mujahideen [Images] to conceal their identity.

The investigating teams say they are probing deeper into the SIMI angle and preliminary investigations show that the banned outfit was behind the blasts.

Sadiq, according to the police, had played a key role in the Surat [Images] riots. He was staying at Gurapanapalya in Bangalore, the area which incidentally housed the SIMI office before it had been banned.

The police have seized Sadiq's mobile phone and are checking the call records of both his cell phone and land phone.

It may be recalled that Sadiq had been questioned following the arrests of SIMI operative Riazuddin Nasir and Yahya Kamakutty in Karnataka earlier this year.

Karnataka Police had cracked down on SIMI operatives and their interrogation led to the arrest of 10 SIMI activists at Indore in Madhya Pradesh [Images].

With the role of the SIMI becoming stronger in the case, the police are cracking down on local SIMI groups in the state. The police are trying to find more clues by cracking down on these groups. More arrests are expected in the next couple of days, an officer added.
