"They were looking at suspects who were breaking into cars when a vehicle sped through the parking lot clipping one of the officers" before 8:30 p.m. Jan. 29, Paramus Police Chief Robert Guidetti said.
The vehicle -- described by witnesses as a black Honda CRV -- kept going and sped off.
Fellow officers took their colleague to The Valley Hospital in Ridgewood with a knee injury, responders said.
Guidetti's detectives, meanwhile, interviewed witnesses and reviewed surveillance footage at the mall just off Routes 4 and 17.
It was the second police officer injured in a crash in Bergen County on Monday.
A Fair Lawn police officer in an unmarked sedan was injured in a collision with an SUV while responding on Monday to a shoplifting at a local CVS.
