In the murder case filed over the death of former Bangladesh Air Force Flight Lieutenant KM Tahsif Souri, his “junior friend” Ahmed Shahriar Reza Dwip has been arrested as a suspect. A court has ordered him to 4 days of police remand for questioning.
On Saturday (31 October), after a hearing, Dhaka Metropolitan Magistrate Hasib Ullah Piyas issued the remand order. Dwip was produced in court around 2:15 pm that day. Inspector Firoz Uddin of the Tongi outpost of River Police applied for a 7-day remand in the interest of a proper investigation.
According to the application, the deceased KM Tahsif Souri was a former Air Force officer who lived in a flat in Sector 18 under Turag Police Station. At around 6 pm on 27 October, the accused Ahmed Shahriar Reza Dwip called him out. He has been missing since then.
The next day, on 28 October at around 4:30 pm, police learned via the national emergency service 999 that an unidentified body was floating in the Turag River near Rajabari Ghat under Uttarkhan Police Station. Police recovered the body; during the inquest, his identity was established from an iPhone found in the deceased’s trouser pocket.
Based on IT and confidential information, it was learned that the accused Dwip had taken the deceased Souri to the Mazar Basti area under Tongi West Police Station on the day of the incident. In initial questioning, Dwip admitted that the deceased Souri was his senior elder brother. Despite the age gap, he claimed they had a friendly relationship.
Preliminary investigation found clear evidence of Dwip’s direct involvement in the killing. The application stated that remand and interrogation were essential for the investigation and to prevent the accused from getting bail and obstructing the probe.
Reasons cited for seeking remand:
- To uncover the main mystery and motive behind the killing.
- To identify and arrest other unknown accused involved in the killing.
- To recover evidence used in the killing and other necessary items for the case.
- To recover the personal motorcycle used by the deceased former Air Force officer Tahsif Souri.
- To specifically identify the main location where the killing took place.
During the hearing, Dwip was brought into the courtroom. Additional Public Prosecutor Azizul Haque Didar argued for the remand on behalf of the state. The court then issued the remand order.
On the evening of 27 October, Tahsif left home after being called by junior friend Dwip and went missing. The next afternoon, River Police recovered his body from the Rajabari Ghat area of the Turag River. His father, KM Enayetul Karim, filed a case at Uttarkhan Police Station in the capital at 1:05 am on Friday night, naming unknown persons as accused. Police later showed Dwip arrested as a suspect in this case.
Dwip’s statements to the PBI
Dwip, who spent several hours with Tahsif before he went missing, has given conflicting accounts. Earlier, he told media that the two visited a motorcycle workshop, had dinner at a restaurant in Uttara (including mentions of Ruap Complex or Ashkona), and parted ways around midnight in the House Building area, after which he returned home.
During PBI questioning, he claimed that while they were talking near the river (Mazar Basti / Rajabari Ghat area, described as a drug hotspot), some people—reportedly wearing police uniforms—chased them. Tahsif jumped into the Turag River, while Dwip fled (one account says he hid behind a boundary wall or BIWTA pillar before leaving and returning home around 2:30 am). PBI officials are verifying these claims, noting inconsistencies, and investigating whether the pursuers were actual police, drug traffickers, or others. Based on his information, a motorcycle believed to be Tahsif’s (a black Suzuki Gixxer 150 without a number plate) was recovered near the river.
Tahsif’s comments and reported fears
In a July 2026 podcast interview on the YouTube channel “Speak with Rashid,” Tahsif addressed allegations linking him to the viral video of Sheikh Hasina’s departure from Bangladesh on 5 August 2024 (he or a colleague was accused of recording or circulating it) and claims by the newspaper Amar Desh of links to India’s RAW intelligence agency. He dismissed the RAW-related report as “propaganda,” challenged the lack of proof for his involvement in the video, and suggested the allegations may have contributed to his departure from the Air Force. He said he faced social embarrassment and harassment afterward and declined to disclose everything about the events, citing some constraints. ISPR had stated that he and another officer were retired through regular process unrelated to the allegations.
Separately, his father told media that Tahsif had sometimes said he was “a bit apprehensive” or felt unsafe / feared for his safety, though he never explained why or reported specific threats. The family has strongly alleged murder (not suicide or accidental drowning), noting Tahsif was a trained pilot who knew how to swim and had completed self-defence and swimming training. They reject the idea that a commissioned officer would jump into the river out of fear of a chase.
The case remains under investigation by River Police (with prior involvement by PBI). Autopsy and other reports are pending, and authorities are examining the cause of death, movements that night, and any possible links to the earlier controversy.
