Delhi gangrape in bus: After night of horror, medical student battling for her life, cops arrest 4

"One of the phones was active and it helped us to pinpoint on them," a senior police official said.

Police have recovered the iron rod which was used to assault the victim and her male friend, the official said.

Students, who were protesting outside the police station, said Delhi cannot stand women stepping out of their homes at night.

"We try to create awareness in every locality but nobody cares. The government and police must ensure that harassment of women in Delhi should stop. Only CCTVs won't work," one of the protesters said.

Chhaya Sharma, Deputy Commissioner of Police, South, told reporters, that both the girl and boy had "put up a fight" with the men.

She said the bus which the duo boarded was not in commercial service and they were picked up by the driver from Munirka bus stop for Rs 10 each to be dropped at Palam.

"When they boarded the bus, there were a few other men as well in the vehicle. There was an argument between the male friend and others... As of now, we can confirm the involvement of four men. They beat them up brutally using iron rods," she said.

She also said seven people appeared to be inside the bus but only four were involved in the incident. Sharma said both victims are under treatment and police got some clues from the male friend.

The police official said the cops came to know of the incident after the victims were dumped near Mahipalpur flyover. They were rushed to AIIMS from where the girl was shifted to Safdarjung Hospital.
