Three members of a family were found hanging inside the Indian Institute of Technology - Delhi premises, the police said on Saturday.
Bodies of Gulshan Das, a senior lab assistant in the Department of Bio-Chemistry at IIT, his wife Sunita and his mother Kamta were found hanging inside Kumar's official accommodation late on Friday night. No suicide note was recovered, said the police.
According to the police, they had reached the IIT campus after receiving a panic call reporting domestic violence by Sunita's mother, who was unable to reach her daughter.
Upon reaching the flat, it was found bolted from inside. The police broke open the door to find three bodies hanging from the roof.
"The women were hanging in separate bedrooms with dupattas tied round the fans. Gulshan was hanging in the corridor with a dupatta tied to an overhead rod/pipe," said DCP (South-West) Devender Arya.
"No external injuries were found on any of the bodies and no suicide note was recovered from the house," police said.
"We have sent the bodies for post-mortem. Gulshan's family, based in Haryana, has been informed of the tragedy," said Arya.
The police suspect it to be a case of suicide.
