The 46-year-old Humayun, arrested on charges of theft, committed suicide by immolating himself on the premises of the Kanathur police station, on Monday.
Kanathur police identified the deceased as a carpenter and a resident of Jai Nagar, Panayur, who was arrested on Sunday evening following a complaint of theft lodged by a woman resident of Kanathur.
'Humayun , who was to be remanded to custody on Sunday, was sitting on the Kanathur station premises as there is no lock-up facility. There was an SSI and a sentry on duty. Around 12.30 am, he doused his body a can of kerosene, which had been seized in another case, and ran outside with a matchbox,' an officer said.
Humayun set himself ablaze immediately, police said. The two policemen put out the flames and rushed him to a private hospital nearby. He was shifted to Government Kilpauk Medical College hospital, where he succumbed to his burns at around 7.30 am.
Family members, including his wife, Yasmin, claimed that police personnel had brutally assaulted him and set him ablaze. They refused to claim Humayun’s body, wanting a thorough probe into the death.
