A 26-year-old man allegedly committed suicide after slitting the throat of his live-in partner in south Delhi as he suspected her of infidelity, police said Tuesday.
The man has been identified as Avishek Mondal, they said.
A suicide note was found from the spot in which the man mentioned that he suspected his partner of infidelity and was possessive about her. He had also scribbled on walls and mirror about his doubting the woman, a senior police officer said.
On Monday evening, a call was received from a woman that the door of her floor floor flat in Chhatarpur Extension was locked from inside, he said.
The caller, Parboni, told police that she shared the flat with her friend, the officer said.
A team of police reached the spot. The front door of the flat was broken and a woman was found lying in a pool of blood and Avishek Mondal was found hanging from the ceiling fan, police officer Vijay Kumar said.
Both of them were shifted to a hospital where the doctor declared them brought dead, he said.
The body of the woman has been handed over to the family members after postmortem, police said.
Police said the man and Parboni were old friends and were from West Bengal. The flat was taken on rent by the three of them a few months ago.
The man, a digital marketing executive, was in a live-in relationship with the 23-year-old graphic designer. There were frequent quarrels between the two recently, they said.
A few weeks before the incident, police learnt, the couple had a fight following which the man moved out of the house.
On the day of the incident, Mr Mondal had come back in the morning on the pretext of collecting his belongings, the officer said.
Three teams from the Forensic Science Laboratory inspected the home on Monday night and recovered a knife.
On Tuesday, the teams again visited the spot to inspect a laptop and mobile phones of the man.
Police said further investigation was underway.
