Locals said he was returning from his chamber around 9:30pm last night when unidentified criminals stabbed him indiscriminately.

Locals rushed him to Kaliganj Upazila Health Complex where doctors declared him dead, said Anwar Hossain, officer-in-charge of Kaliganj Police Station.

Razzak was a loyal member of the Shia community, said Feroz Hossain, headmaster of Bejpara Higher Secondary School. "He was an honest man, often preached religion."

Wife Shahnaj Parvin said a few months back Razzak received an anonymous call demanding Tk 2 lakh as extortion from him. "He had no enemy. He was a doctor and Shia follower."
