The college student allegedly raped by four Presidential Body Guards on October 8 identified three of the accused -- Manish, Satinder and Kuldeep -- during a Test Identification Parade on Friday, police sources said.

Earlier, the victim had identified one of the accused, Harpreet.

The identification has strengthened the police case.

The police are now waiting for a report from the Central Forensic Sciences Laboratory to corroborate the evidence in the case.

The accused had allegedly committed the crime when the girl had gone to the Buddha Jayanti Park with a friend.

While Harpreet was arrested the same day, the others were nabbed on Thursday, the sources said.
