Unable to bear her husband's harassment, a woman set him ablaze in Gobichettipalayam Taluk in the district, police said on Thursday.
Police said the 50-year-old Palanisamy used to drink and beat Senniammal, five years younger to him, and they often quarrelled.
On Saturday last, Palanisamy came home in an inebriated state and quarrelled with Senniammal. Unable to put up with his behaviour any more, she pushed him down, poured kerosene and set him ablaze. He died on the spot, police said.
She then put the charred body in a garbage bin and covered it with debris and mud.
Police said out of fear, she informed the Ayyalure Panchayat President about the murder.
Police, who were informed, arrested the woman and exhumed the charred body, the sources added.
