The Rapid Action Battalion (RAB) has taken former OC of Teknaf police station Pradeep Kumar Das and two others into custody for remand over the death of retired Bangladesh Army Major Sinha Md Rashed Khan.

They were taken to RAB office from the Jail at Cox’s Bazar at 11:30am on Tuesday, said Md Mokammel Hossain, superintendent of the district jail.

Earlier on Monday, a probe committee formed by the home ministry quizzed Pradeep, Inspector Liaqat Ali and Sub-inspector Nandadulal at Cox”s Bazar Jail gate.

On the night of July 31, Major Sinha was shot dead at a police checkpoint on Marine Drive Road between Cox’s Bazar and Teknaf.

On August 5, Sinha’s sister Sharmin Shahriar Ferdous filed a case with the Senior Judicial Magistrate Court of Teknaf against nine policemen, including Pradeep and Liakat.

On August 6, seven of the accused surrendered in court, which sent them to jail after scrapping their bail pleas.

Soon after the court’s order, RAB, which is in charge of the probe, moved a petition for taking the suspects into custody. The court remanded Pradeep, Liakat, and Nanda Dulal for seven days and gave investigators two days to interrogate the four other suspects.

The court later issued arrest warrants for the two fugitive suspects named in the case.

RAB has already started interrogating seven suspects, including four policemen.

Assistant Sub-Inspector Liton Miah, and Constables Safanur Karim, Kamal Hossain, and Abdullah Al Mamun, are in RAB custody.

The elite police unit is also questioning three witnesses in the case started by police.
