Lawrence police on Monday were looking for a suspect in a Sunday night stabbing that sent a 15-year-old boy to the hospital.

Sgt. Ted Bordman said the incident began with an altercation between two groups of people in the parking lot of Hobbs Park near 11th and Delaware streets at 11:56 p.m.

Police received calls about the fight and learned that two cars had left the scene.

Bordman said an officer pulled over one of the vehicles, a black Ford Escort, near Seventh and Rhode Island streets. Inside the car, the officer found the stabbing victim and a friend who was rushing him to Lawrence Memorial Hospital.

Medics arrived at the scene and transported the teen to the hospital where he was treated and released, Bordman said.

The other vehicle that left the scene was a light blue Chevrolet Suburban driven by a man in his 20s. Bordman said police identified the man as a person of interest by interviewing people at the scene.
