Srinagar, Oct 7 (IANS): Four people, including three policemen, were arrested in Kashmir's Anantnag district Sunday for allegedly beating a woman to death during a police search for contraband drugs, a police official said.

"Three policemen and the son-in-law of the woman have been arrested. Further probe will be done after the autopsy report," the police official said.

People in Ahlaan Gadool village in the Kokarnag area of Anantnag Friday staged a protest demonstration after the death of 65-year-old Mukhti.

Family members of the woman alleged that she was ruthlessly beaten up during a police raid Friday. She complained of a chest pain and later passed away.

The villagers alleged that police raided the woman's house based on a false information given by her estranged son-in-law, who works as a police informer, that there were stocks in the house of some contraband herb called dioscerea, which is found in the valley forests and used in making drugs.
