But it's not yet known what sparked the shooting, which occurred around 1:30 a.m. Wednesday on North Broad Street.
Witnesses told responding offices the shooter was in the van that had just fled the scene. The officers briefly pursued the vehicle as the driver reached speeds of up to 100 mph, but the chase was soon called off.
The two people who were shot were both hospitalized in stable condition. But their names and further details on their injuries were not disclosed.
The shooter remains at large.
