Metropolitan Magistrate Abdur Rouf Khan granted the remand prayer when Hannan, Abdur Rahman, Badsha Miah and Saibal Saha Partha were produced before the court at about 2:30pm yesterday.

The four persons picked earlier on different charges from different places in the city were shown arrested on Wednesday in the case filed by police on August 22, a day after the grenade attacks on an Awami League (AL) rally.

In the petition filed by the Criminal Investigation Depa-rtment (CID) on Wednesday, investigation officer claimed he collected important information about their involvement in the grenade attack, which killed 20 people and injured over 200 with AL President Sheikh Hasina surviving barely. But more interrogation is required to find out the motive behind the attack and whereabouts of their accomplices, he stated.

Advocate Gyanendra Chandra Biswas, the defence lawyer for Partha, submitted a petition seeking bail and cancellation of the remand prayer.

Moving the petition, the lawyer said Partha, who was arrested initially on August 26 allegedly for sending email to the daily Prothom Alo with a threat to kill Hasina within seven days, was implicated in the case as part of a conspiracy.

Partha was remanded for seven days twice, but police failed to come up with any concrete evidence of his involvement.

He was physically and mentally tortured when police quizzed him in previous remands, the defence lawyer argued. But the general recording officer opposed the move and prayed for a seven-day remand.

Upon hearing, the court rejected the bail petition and placed all the four on a five-day remand.

The Rapid Action Battalion (Rab) arrested Abdur Rahman from his house at Sector 10 in the Suburban Uttara on September 4 and recovered a foreign revolver with 13 bullets. He was also taken on a 10-day remand for interrogation.

The other two-- Hannan and Badsha -- were arrested on September 8 from Mogbazar on charges of bomb explosion during an AL-enforced hartal. They were sent to Dhaka Central Jail the next day, as investigation officers did not seek for remand.
