The bodies of a 22-year-old woman and her two children were found hanging at their house in Delhi, police said on Friday.
The incident occurred on Thursday in northwest Delhi's Shakurpur area and the police were informed about it at around 10.40 pm.
The woman's husband was at work when the incident took place, the police said, adding that on returning home, he saw the bodies hanging.
