There has been no breakthrough in the murder of a 17-year-old girl who was found killed in Delhi on the New Year's day, police said on Monday.
"The investigation is going on," a police official said after Jennifer was found murdered in Dwarka in southwest Delhi Saturday.
She resided with her brother in the servants quarters of the Lady Hardinge Hospital in New Delhi area and went out for a New Year party on Friday.
"We have detained four suspects from the locality where the victim resided," Sharad Aggarwal, deputy commissioner of police for southwest, told IANS.
The four who have been detained went missing soon after the incident.
"We are questioning them," Aggarwal said.
According to police, Jennifer was first strangled with her pair of jeans and then her face was smashed with a stone to make identification difficult.
Police claim there were no injuries on Jennifer's private parts and it was yet to be established if she was raped.
"The preliminary medical reports state that the girl had sexual intercourse prior to her murder but there were no injuries on her private parts. We are investigating the case from all possible angles. We cannot confirm this to be a rape as of now. We are trying to gather leads in the case," Aggarwal said.
He said they were awaiting the post-mortem examination report.
Another police official said Jennifer told her brother at around 5.30pm on Friday that she was going out with her friends to a party.
The body was discovered by a passer-by around 3.30pm on Saturday in Dwarka area, and he immediately informed the police.
