Candlelight vigil held for NRI student Anmol Sarna, who was killed at a party on Friday night
Three days after a 21-year-old NRI died after attending a party in South Delhi, the police have not arrested anyone.
"It is a cold-blooded murder, his friends are responsible," said Anmol Sarna's mother, Shobha. The family had moved back to India after 27 years in the US.
The four friends who were with Anmol on the night that he died have been questioned, but there is no evidence against them, police sources said.
Anmol Sarna was spending his holidays with relatives. He had finished high school in the US and was to join a hospitality institute in California next month.
On Friday night, he was at a friend's house, the police said. He was spotted bleeding on the road by a passerby who phoned the police for help. He died after being moved to hospital.
Doctors have told the police that he had a large and deep injury on his forehead. The police are not sure if he was attacked or hit his head by accident on a wall.
Anmol moved to Delhi to his grandmother's house in December, according to the police.
