Sham's wife Kajal said he was returning home on the night of March 13 when Jasbir, Deepak and Lovely had a fight with him near the Batala road. "When he refused to give them money, they pushed my husband's head into a furnace. He was also beaten up with a stick," she added.
Amritsar police commissioner Ram Singh said Jasbir and Sham knew each other, adding that the victim had apparently fallen on the furnace accidentally during a fight.
However, on the basis of Sham's statement, the police registered a case and have started a probe.
In his statement, Sham alleged that he was coming back from work with a liquor bottle when the accused told him to hand it over. When he refused, they started beating him up. Later, the constable allegedly pushed Sham's head into furnace before taking away Rs. 7,000 from him.
No arrest has been made so far.
