The police said the criminals fired at 35-year-old Siddhartha Kundu, Youth Congress president of Northwest Delhi Lok Sabha constituency, when his car was standing at the Mohan Nagar intersection around 2.30 pm.
Mr Kundu, an advocate, told the police that he was on his way to Ghaziabad court in connection with some litigation. He was sitting on the front seat of the car.
As soon as the car reached the Mohan Nagar intersection, two young boys overtook the car from left side and fired two shots at the car.
One bullet pierced through the bonnet of the car, the police said. Mr Kundu had a narrow escape.
Sahibabad police station SHO Upendra Yadav immediately reached the spot and forensic teams were summoned.
Kundu informed the police about a property dispute in his family. The police, however, could not find an eyewitness to the incident. Further investigations are on into the matter, Mr Yadav added.
