The police arrested a 32-year-old man on charges of murdering his father after a tiff with his brother.

The police said, the suspect Palanivel, an electrician and a resident of Nagammai Nagar in Thirumullaivoyal, had come home around 10 p.m. on Wednesday and demanded that his brother Vinayagamoothy (30) go buy dinner for him.

When the latter refused, the brothers got into an argument and attacked each other. When their father Mariappan (65) tried to intervene, an enraged Palanivel hit his father and brother with a club.

They suffered severe head injuries and were admitted to Rajiv Gandhi Government General Hospital.

Mariappan did not respond to treatment and died on Thursday evening, the police said.

The Thirumullaivoyal police booked Palanivel for murder and arrested him. He was remanded to custody and sent to Puzhal prison.
