Police are searching for a young woman in connection with the mysterious death of former Bangladesh Air Force officer Flight Lieutenant K. M. Tahsif Sauri.
 
Before going missing, Tahsif and his friend Dwip were seen with the young woman at a restaurant and bar in Uttara.  
 
Meanwhile, the Naval Police have placed Ahmed Shahriar Reza Dwip, also Tahsif’s junior friend who was arrested in a murder case filed by his father—on a four-day remand.
 
During interrogation, Dwip claimed that Tahsif jumped into the river after being chased by police in the Tongi Mazar Bosti area. However, investigators are examining whether this statement is an attempt to frame the incident as a mere accident or if there is a Dwip’s conspiracy behind it.  
 
According to sources close to the investigation, police recently collected a new CCTV footage to unravel the mystery of the death. According to the footage, Tahsif and a 24-25-year-old young woman arrived on a motorcycle at the "Nest Restaurant and Bar" in Sector 11 of Uttara at 10:17 PM on October 27.
Dwip was also with Tahsif at the time, wearing a helmet.   The footage shows the young woman—wearing a T-shirt, trousers, and sneakers—holding a white polythene bag. They spent about an hour and a half there. Later, Tahsif and Dwip went to the Tongi Mazar Bosti area. It could not be confirmed whether the young woman accompanied them to Tongi.
 
Police believe that if she can be identified and interrogated, crucial information just before Tahsif went missing will be uncovered.  
 
The remand application stated that at around 6:00 PM on October 27, Tahsif left his residence in Sector 18 of Uttara upon Dwip’s invitation. The following day, on October 28, at around 4:30 PM, his floating body was recovered from the Turag River adjacent to Rajabari Ghat in Uttarkhan Police Station based on information received via the national emergency service number 999. His identity was confirmed using an iPhone found in his trouser pocket.
 
Later, through information technology and confidential sources, it was confirmed that Dwip had taken Tahsif to the Tongi West Police Station Mazar Bosti area on the night of the incident.
 
The police mentioned in court documents that preliminary investigations found evidence of Dwip’s direct involvement in the incident.  
 
During interrogation, Dwip told police that upon seeing two police officers in uniform in the Tongi Mazar Bosti area, they got scared and ran in opposite directions.
 
At one point, Tahsif jumped into the Turag River. However, police suspect they might have been chased over suspicions of drug use or another crime.
A cloud of confusion surrounds the identity of those two police officers, the actual reason for the chase, the truth about Tahsif jumping into the river, and how Tahsif’s motorcycle arrived at the scene.
 
Investigators say there are extreme inconsistencies and contradictory information in Dwip’s statements.  
 
Naval Police Dhaka Range Superintendent of Police Abdullah Al Mamun stated that Dwip was with Tahsif throughout the entire sequence of events. Therefore, interrogating him is likely to reveal the real mystery behind the death.
 
The court has granted a four-day remand for him. Investigators are thoroughly verifying whether he genuinely jumped into the river due to police chasing them or if there was a pre-planned incident behind it. In addition, efforts are underway to identify everyone Tahsif met after leaving home, conduct a forensic examination of his iPhone, and recover the motorcycle and other evidence.  
 
Earlier on Thursday night, the PBI (Police Bureau of Investigation) detained Dwip and, after visiting the scene with him, handed him over to the Naval Police on Friday night.
 
Past midnight at 1:00 AM on Friday, Tahsif’s father, K. M. Enayetul Karim, filed a murder case against unidentified individuals at Uttarkhan Police Station.
 
Showing Dwip arrested in that case, police produced him before the court on Saturday and prayed for a seven-day remand, while the court granted a four-day remand.
