The High Court has asked for four police officials to turn up at a lower court, including former Ramna police chief Mahbubur Rahman.
Three others accused were assistant sub-inspector Rezaul Karim, Naser Ali and Nilkhet police check-post sargeant Anwar Hossain.
The bench of two High Court (HC) justices Sharif Uddin Chaklader and Mohammad Fazlur Rahman ordered the four accused to appear before the court.
On Thursday, a Dhaka court had issued arrest warrants against the accused. On Sunday, the accused, however, sought bail from the HC, but were rejected.
The HC on Sunday ordered that they should not be harassed before Oct 26.
Some criminals stabbed the late Humayun Azad on his way home in front of Bangla Academy on Feb 27, 2004, leaving him seriously injured.
Abbas, a student of political science of Dhaka University, was suspected to be linked to the attack and his statements were allegedly taken in remand through torture.
The former joint general secretary of Dhaka University’s Sir F Rahman Hall later secured bail.
Later on Mar 5, 2008, he filed the case with the Dhaka Chief Metropolitan Magistrate’s Court, accusing former home state minister Lutfozzaman Babar, Mahbubur Rahman and three other police officials for torture.
On Aug 19, 2010, the Criminal Investigation Department pressed charges against four police officials, including Rahman.
Babar’s name was not included in the charge-sheet as he was not found to have any links with the incident.
