Two unidentified persons who were on a motorcycle intercepted the car and signalled its driver to stop.
Presuming that some AAP supporters wanted to talk with the leader, the driver stopped the vehicle.
However, as soon as the car stopped, the two men smashed the windshield with an iron rod and fled.
A complaint has been made to the police in this regard, the sources said.
Jaihind, who is contesting from Rohtak which is represented by two-time MP and Chief Minister's Bhupinder Singh Hooda's son Deepender Singh Hooda, recently drove to file his nomination papers in Kejriwal's car.
