Shahid Chairman was taken on remand for the second time while three others -- Sobhan Driver, Kala Mahbub and Md Shahjahan, chairman of Hiledhar union, -- were placed on remand on Sunday. All the four were brought to the Rab-7 HQs yesterday for interrogation.

Rab sources said they were quizzing all the four suspects, but refused to say whether they were brought face to face.

Shahidul Islam alias Shahid Chairman, a Union Parishad chairman, has given the same information he divulged during the first phase of his remand, they said.

Sobhan, the driver of a microbus used in the abduction who earlier made a confessional statement, did not give any new information on the first day of his four-day remand.

Kala Mahbub, now on a five-day remand, remained tight-lipped, sources said.

The Rab officials, who remained mum about the findings in the interrogation, said they have extracted enough information.

Jamaluddin Ahmed Chowdhury, also a leader of Chittagong (south) district unit of ruling BNP, was abducted from Chandgaon Residential Area while returning home from his place at Chawk Bazar on July 24, 2003.
