The incident took place last night when a police team, including the SHO of Sector-29 police station, was patrolling near a shopping mall on M G Road here.
"A CCTV footage shows the SUV with tinted glasses speeding towards the police picket even after policemen indicated it to stop for checking," a senior police officer said.
"The car hit a police vehicle when SHO Vikas Kaushik tried to stop it, injuring three pedestrians including two women who were leaving the mall," the officer said, adding the miscreants then managed to escape.
"We are trying to identity the accused by examining the CCTV footage. The vehicle had Delhi registration number," he said.
