Two women from Mizoram were found dead in mysterious circumstances here on Friday with police suspecting that the deaths may have been caused by a drug overdose.

Additional Deputy Commissioner of Police Chinmoy Biswal told  that Clara and Rakil, both 22, had partied with their friend Jenny in her rented accommodation in Munirka village on Thursday night.

Clara was living in Delhi with her cousin Liankhanmay and her friend Rakil visited the city from Lucknow on Thursday evening. 

The two went to Jenny's room for the party, Biswal said.

While Jenny, who works at a Gurugram-based call centre, left for her office after midnight, Clara and Rakil stayed overnight.

When she returned on Friday morning, she found her room locked from inside, Biswal said, citing Jenny.

"When no one responded to her calls, she peeped inside. She saw Clara and Rakil were lying unconscious. She called Liankhanmay for help," Biswal said.

They somehow managed to open the door and took them to Safdarjung Hospital, Biswal said.

"Doctors at the hospital informed police at 9.20 a.m. about their deaths caused by suspected drugs and alcohol overdose," the officer said.

A medical board to carry out an autopsy "to ascertain the cause of death" has been constituted, said Biswal.

The room where the women were found dead has been sealed and was being inspected by forensic experts.

Clara was presently unemployed while her cousin Liankhanmay works in a call centre.
