Detectives yesterday arrested two suspects from Dhaka and Tangail in a case filed for killing former chairman of Power Development Board (PDB) Khijir Khan.

The arrestees are Tariqul Islam Tarer alias Mithu, an alleged organiser of banned Islamist militant outfit Jamaatul Mujahideen Bangladesh (JMB) and Alek Bebari, said an official of Dhaka Metropolitan Police's media section.

Two laptops and two cameras, which were stolen from Khijir Khan's house, were recovered from Tariqul's possession, he said.

Further details could not be known immediately.

Detective Branch of police called a press conference at the DMP media centre around 11:30am today to share information, the DB official said.

A group of unidentified assailants murdered Khijir, also a freedom fighter, by slitting his throat after tying up his family members in his Maddhya Badda house in the capital on October 5.         

The following day, the murder case was filed accusing six to seven unnamed people.

Meanwhile, at a human chain in front of Jatiya Press Club yesterday, Engineers Institution Bangladesh demanded that the killers be arrested and punished. The speakers said if the killers were not brought under trial, such murders over "differences of religious views" would keep on taking place.
