A 40-year-old man has been arrested for allegedly duping owners of used cars by mortgaging their vehicles in suburban Oshiwara here, police said.

The Oshiwara police arrested Sanjay Senani, who used to rent used cars and later allegedly mortgaged them to earn quick money, an official said. The fraud came to light when two people approached the police with a complaint that the accused was not paying rent or returning their car, he said.
