A Dhaka court has placed Jerika Tasnim Disha, 19, on a four-day remand in connection with the death of former Bangladesh Air Force officer KM Tahsif Souri, whose body was found floating in the Turag River a day after he went missing.
Dhaka Metropolitan Magistrate Md Ripon Hossain passed the order on Sunday.
The Naval Police arrested Disha, believed to be Tahsif’s friend, from the capital’s Kafrul area on Saturday night with the assistance of female police officers.
She was produced before the court with a prayer for a seven-day remand for in-depth interrogation to uncover the circumstances surrounding the incident, said Abdullah Al Mamun, superintendent of police of the Dhaka region of the Naval Police.
Meanwhile, Sunday was the first day of the four-day remand of another accused in the case, Ahmed Shahriar Reza Dwip, an acquaintance of Tahsif. According to investigation sources, investigators obtained several important pieces of information from Dwip during the first day's interrogation.
Sources involved in the investigation said a joint probe by the Police Bureau of Investigation (PBI) and the Naval Police, with the assistance of information technology, had uncovered several significant details.
An analysis of CCTV footage from various locations in Uttara showed that Tahsif visited Nest Bar & Restaurant in the area with Disha on the night of October 27, shortly before his death.
The two were also seen having a meal together at CP Five Star that evening and spending time together at a motorcycle garage.
The investigation also found evidence of multiple phone conversations between Tahsif and Disha through an examination of his call detail records (CDR). Investigators also gathered information indicating that the two had travelled together by motorcycle to various places.
Police said the preliminary investigation had found evidence of Disha's direct or indirect involvement in the killing.
Investigators believe both accused need to be questioned to cross-check Dwip's statements with those of Disha. After the first phase of remand, investigators may seek another remand for Dwip if necessary.
