The case was filed for bomb blasts on a rally of the Communist Party of Bangladesh (CPB) at Paltan Maidan on January 21, 2001. Five people were killed and 50 others injured in the incident.

The Criminal Investigation Department (CID) accompanied by Rapid Action Battalion (Rab) produced Hannan before the Chief Metropolitan Magistrate's (CMM) Court, Dhaka at 1:30pm yesterday under a tight security and submitted a petition for showing him arrested in the case.

The CID also submitted a petition for placing him on a ten-day remand for interrogation in connection with the blasts.

On completion of Hannan's eight-day remand in the Ramna Batamul carnage case, CID Inspector Abu Hena Mohammad Yusuf, also the investigation officer (IO) of the case, said Hannan gave important information about the carnage and should be confined in jail until the investigation completes.

In the forwarding report placed before the court, CID Assistant Superintendent of Police and IO of the CPB bomb blast case Syed Momin Hossain said Hannan might be involved in the incident. The Huji leader needs to be intensively interrogated to find out vital clues to the bomb attack and the whereabouts of his accomplices responsible for it, the IO added.

After the hearing, Metropolitan Magistrate Shafiq Anwar granted the petition for showing Hannan arrested in the case and placed him on the remand.

Hannan was arrested at Madhya Badda in Dhaka on October 1 last year after several years of absconding. Later, he was shown arrested in different cases filed with different police stations in connection with the serial bomb blasts across the country last year.

Following the attack on the CPB rally, CPB President Monzurul Ahsan Khan filed a bomb blast case with Motijheel Police Station saying a group of anti-state conspirators made the attack.

Police arrested 12 people at that time but the CID submitted the final report on December 17, 2003 as correct, impartial and reliable pieces of evidence were not found to prove the charges against the arrestees.

The investigation officer (IO) said he will press charges if sufficient evidence is found against the arrestees.

The IO submitted a petition with the CMM Court for reinvestigation into the case on January 27 last year and the court directed him for fresh probe into the case after two days.
