Srinagar, July 10 (ANI): In a bid to disperse frenzied protesters, who were demonstrating against the death of a 20-year old student in Srinagar, police used tear gas and fired in air on Friday.

The protestors blame police and the security forces for killing 20-year-old man after his arrest.

The protesting mob threw stones at the police personnel and forced business establishments to down the shutters.

However, police has said that the youngster was killed by unidentified criminals.

Reportedly, the deceased went missing last week and his body was found near a graveyard in Srinagar on Wednesday.

Meanwhile, continuing with their crackdown on stone pelters and anti-national elements, the state police have picked up another 100 people for allegedly fomenting trouble.

The number of total arrests under Public Safety Act has reached above 400, according to official sources.

Over three dozen people were picked up from the Srinagar, Baramulla and Anantnag.

As many as 50 people were picked up from Shopian district, which has been witnessing frequent strikes over the alleged rape and murder of two women.

According to sources, the authorities decided to clampdown on stone pelters as they used to bring the Kashmir Valley to a grinding halt over irrelevant issues.

Some of the stone pelters have even been slapped with serious charges of attempt to murder, sources said. (ANI)
