Vijay Ramlal Dhavan, who runs a real estate firm, was arrested in Delhi on June 1 and brought to Mumbai for stealing a Mercedes registered in his name.
The next morning, the car was missing and police believe Dhavan stole it using a second set of keys.
On May 27, Ahmed and Singh filed a police complaint on Dhavan's insistence. The RAK Marg police station registered an offence of theft against unknown persons but got suspicious that the Mercedes had been brought to Mumbai from Delhi for a friend.
They contacted a Mercedes showroom and found out that this particular model car can only be opened using one set of keys, according to HT. The police also learnt that Dhavan had recently ordered a second set of keys.
