New Delhi:  A 40-year-old taxi driver killed his wife and neighbour being suspicious over her infidelity towards him, in northeast Delhi's Gokulpuri area on Saturday.

The deceased have been identified as Kavita alias his wife (35) and Aakash (23), nephew of Arun's landlord. Aakash had cleared Delhi Police's recruitment exams for head constable's post and was awaiting results. The accused, Arun Chauhan, is on the run.

Arun had borrowed money from his nephew sometime back but had not paid the rent for the past two months due to which the two had frequent arguments.

Arun lived with his wife, son (9) and daughter (11) at a rented accommodation in lane number 7 of Ganga Vihar colony. Family members said the couple had a fight the previous night.

Investigations have revealed that Arun had called up Aakash saying his son had gone missing and he needed help in finding him.

Aakash, his family members said, accompanied Arun on his bike. On the pretext to search for his son in the nearby areas, Arun took Aakash near a drain in Jyoti Nagar and attacked him.
