A delivery boy of a company was robbed of Rs 722,000 by three persons, including a woman, posing as Central Bureau of Investigation sleuths, at Nagpada in central Mumbai.

According to police, the victim and a colleague were travelling in a vehicle to deposit the money at a bank in Bhuleshwar, on Wednesday.

En route, their vehicle was stopped near a signal and two persons entered their taxi. The duo then flashed 'identity cards' and claimed to be CBI officials. The men, in their mid-30s, directed the taxi to another destination, police said.
