A 50-year-old man, who was detained on Monday, allegedly committed suicide by hanging himself from the ceiling of the toilet of Banshtoil Police camp in Mirzapur upazila of Tangail district early Tuesday.

The deceased was identified as Lebu Shikdar, son of Bahar Uddin of Banshtoil village.

Gias Uddin, officer-in-charge (investigation) of Banshtoil Police camp, said police detained Lebu and Mafiz in connection with the killing of one Sakhina Begum of Banshtoil Westpara village on Monday.

“Lebu killed himself by hanging himself from the ceiling of the toilet of the police outpost,” said OC Gias.

Police handed over the body to the family members after postmortem and he was buried in the night.

Protesting the murder, local people blocked the Gorai-Sakhipur-Dhaka road after torching tyres on the road, disrupting vehicular movement for three hours on Tuesday.

According to Aleya Begum, wife of Lebu, she claimed that a team of police led by Daroga Sakhawat and Nesar Uddin picked up Lebu and took him to the police camp forcibly on Monday night and they unleashed torture on Lebu during the whole night. He died there after failing to bear the torture under police custody.

A three-member body was also formed to look into the matter, he said adding “Legal action will be taken against any policemen involved in the death of Lebu.”
