New Delhi, July 23 (IANS): A 25-year-old woman has been arrested for the murder of a senior citizen at his flat in Samachar Apartments in east Delhi's Mayur Vihar, police said on Saturday.

Investigators said the woman was arrested on the basis of circumstantial evidence and with the help of CCTV footage.

The woman informed police that she approached the victim two years ago for a job but the elderly man allegedly sexually exploited her and filmed her in the nude.

The woman has confessed to the crime and told police that she stabbed him to death to avenge sexual exploitation.

The body of Vijay Kumar, 65, with stab wounds was found by his daughter in his third-floor flat in Samachar Apartments.

The incident came to light when Kumar didn't respond to his daughter Ambily's call. She rushed to his flat and found him lying in a pool of blood in his bedroom and raised alarm.

Kumar was alone when the crime took place, the neighbour said. His wife Vasundhra, 60, works in the Income Tax Office here.
