The families of two teenagers, who allegedly committed suicide in a hotel room in southwest Delhi's Dwarka, were not aware about the duo being friends, the police said today.
During the probe, the police have found that they were known to each other for the last couple of years. They are also analysing phone records and their recent activities to find out what triggered them to take extreme step.
No suicide note has been recovered from the room, which they have booked using a mobile app.
The man's family told police he had never mentioned about any woman to them.
Even on Thursday, he had left his home saying that he was going to attend the demo class of Computer Science for his admissions at the IIT.
He had told his parents that he would be staying at his friend's place for studies but had checked into a hotel with the MBBS student.
The woman's family members are too, in state of shock. She never discussed anything related to friendship with any man. She was a first year student at Lady Hardinge medical college.
Police said that they would be questioning their common friends to ascertain what led them to take the extreme step.
