The deceased Abdus Sattar Mandal, 40, was the son of late Sagar Mandal of Belkuchi upazila in Sirajganj, said Shahjahanpur OC Inspector Shafiqul Islam.
Sattar’s family made call to neibours from native village as they could not reach him over telephone, said the OC.
Later, the neighbours found Sattar injured at his residence and rushed him to Dhaka Medical College Hospital (DMCH) where duty doctor declared him dead at 1:15pm, the OC added.
“Sattar was stuck on his head with a heavy object,” said the police official, adding: “He might be killed following previous enmity.”
Police are investigating into the incident and trying to arrest the culprits, said Shafiqul Islam.
The body was kept at DMCH morgue for autopsy.
