An unidentified gang robbed three occupants of a car of Rs 40.78 lakh and 46 gold coins after brutally assaulting them near Namakkal.

The occupants of the car were returning to Pattukottai on Wednesday after a court at Krishnagiri handed over the gold coins and cash to them.

The gold coins and the cash were stolen from the house of one of the occupants of the car  in September 2015.

Four persons were later arrested in this connection and the booty was recovered. It was handed over to them on Wednesday, police told PTI.

All the three were severely injured and were admitted in a hospital.
