Police inspector Pravin Kolhe of the Khinavali police station under Shahapur told PTI that the victim Namdeo Mukne, (50) used to come home frequently drunk.
His son Santosh (22) was annoyed with his father's drunken behaviour and wanted to end the problem, the police official said.
Yesterday afternoon at about 3.30 pm when his father came home heavily drunk and quarrelled with family members, his son allegedly picked up a grinding stone and hit his father with it, after which he died on the spot, the police official said, adding that his body has been sent for postmortem.
