However, no one was injured in the firing by the suspects believed to be four in number, police said.
The incident occurred near Gurdwara Nabha Sahib on Zirakpur-Patiala road in Punjab when the travellers in the car were asked by police to come out for verification.
Acting on a tip off, a PCR vehicle intercepted a white coloured Lancer car at around 12:15 pm as the police had prior information about movement of some suspicious persons in the city, police said.
An alert was sounded in Zirakpur and adjoining areas and police launched a manhunt to nab them but failed to trace them till the evening.
Police could not see the registration number of the vehicle as the number plate was covered with mud.
A case under various sections including section 307 of the IPC was lodged against unidentified persons, police said.
