Mother of Rayhan Ahmed, who died after being tortured in police custody, said the people who helped destroy evidence and helped prime suspect Sub-inspector Akbar Hossain Bhuiyan to flee must be arrested.

Rayhan's mother Salma Begum spoke to journalists at a press conference held at their house in Sylhet city's Akhalia Nehripara area yesterday afternoon.

She said, "We are still in the dark about why they detained and tortured my son in the outpost. The arrested police personnel are not giving confessional statements, which is also suspicious."

Salma said, "My son went out of home wearing a blue shirt, and we found him at the hospital wearing a red one. We want to know who did that as well."

She also said Rayhan's phone was not handed over to the family yet.

In the press conference, she thanked Sylhet district police and others who helped in arresting Akbar.

Sylhet City Corporation Councillor Mokhlisur Rahman Kamran read a written briefing at the conference, where he thanked all concerned who helped to protest and urge for justice to be served faster.

Rayhan (33), a resident of Akhalia Neharipara area, died at Sylhet MAG Osmani Medical College Hospital at 7:50am on October 11, around an hour after he was admitted there by police.

The next day, his wife filed a case accusing several unnamed persons, mentioning that Rayhan was tortured in Bandarbazar police outpost for money which led to his death.

Sylhet Metropolitan Police suspended four personnel, including SI Akbar, who was in-charge of a police outpost.

On October 13, PBI was tasked with the case's investigation.

Akbar ran away after the incident and was later detained on November 9.

Including Akbar, an SI, assistant SI and two constables have been arrested in the case so far.
