The girl's male partner, Virender Singh, with whom she has been staying at the house for the last couple of months, is the prime suspect in the case as he has been untraceable since the time the incident came to light, police said.
"The victim, identified as Juliet was found lying in a pool of blood by her neighbours late last night. She was rushed to Safdarjung Hospital where she was declared brought dead. Her body bore serious head injuries and stab wounds on her abdomen," said a senior police official.
Investigators have prima facie ruled out any racial attack in this case and a manhunt has been launched to trace Virender Singh.
A case under relevant sections of IP has been registered at Vasant Vihar Police Station.
