The incident took place yesterday night when three bike-borne criminals were heading to Narora.
Acting on a tip-off, the state police remained alert and signalled them to stop but they instead fired upon the cops.
In the exchange of fire, criminal Sumit Sharma injured his leg, following which he was arrested.
However, two criminals managed to flee the spot.
Police recovered a bike and an ATM card that was looted by the miscreant. (ANI)
