Police are searching for two vehicles involved in a shots-fired incident south of downtown Sunday night, according to a Janesville Police Department news release.

Officers responded at about 9:30 p.m. Sunday to a report of gunfire near Main and Clark streets. Multiple people reported hearing seven to eight gunshots and vehicles accelerating out of the area, according to the release.

Witness statements and video surveillance revealed two vehicles were involved in a road rage incident and exchanged gunfire, according to the release.

Officers found a shell casing on the road in the 100 block of Clark Street. One residence was struck by gunfire, but no injuries were reported, according to the release.

Both vehicles were described as newer, with one a silver hatchback similar to a Subaru and the other a blue car with tinted windows similar to an Acura TSX. The blue car also has a loud or modified exhaust system.
