It happened around 1:45 Sunday morning near the intersection of 15th Street and Olney Avenue in the Ogontz section of the city.
Authorities say an officer from the 35th district was behind the wheel of a police cruiser when it collided with another car.
The impact of the crash sent the other vehicle into a utility pole, knocking it down.
A small fire ignited in the police cruiser's engine but was quickly extinguished.
Medics transported the officer to Albert Einstein Hospital where he was treated and released. The driver of the other vehicle was also hospitalized for minor injuries.
So far no word what sparked the crash.
