Kolkata, Jul 24 (IANS): Six persons have been arrested for beating a Trinamool Congress supporter to death in Goghat of West Bengal's Hooghly district, police said on Tuesday.

"Lalchand Bag, a Trinamool Congress supporter, was beaten to death on Monday. Based on his wife's complaint we have arrested six persons and the investigation is in process," a senior officer of Hooghly (Rural)District police said.

A local Trinamool Congress leader said the house of the deceased was attacked after they returned from the Marty's Day event in Kolkata.

"Later, at night while returning home, Lalchand was attacked by former CPM workers who had now joined BJP. After being beaten brutally, he was thrown outside the residence of one of our party workers. He was declared dead after being taken to the nearby hospital," the leader said.
