Around 8.20 PM when he reached the Deen Dayal Upadhyay Marg in his Skoda car, three men travelling in a Verna car overtook his vehicle after which he stopped his car, they said.
Two men got out of the car and surrounded Pankaj's vehicle while the third one kept sitting inside. One of them brandished a gun asked him to open the trunk of his car, they added.
After the men fled from there, Pankaj informed police and a case was registered at IP Estate police station.
