One man was arrested early Saturday and another is being sought after a road rage disturbance that led to gunshots, Lawrence Police said.

The incident began about 2:30 a.m. in the 1000 block of North Second Street when a dispute developed between two men in a car and a man and woman in a truck. The car’s occupants reportedly threw beer bottles at the truck and fired two or three gunshots at it, Sgt. Susan Hadl said. No one was injured.

The rolling disturbance continued across the Massachusetts Street bridge and resulted in a collision between the two vehicles. The car became disabled on Sixth Street. The couple in the truck called police, Hadl said.

Police found a Topeka man in his late 20s at the disabled car and took him in for questioning. He was later arrested and taken to the Douglas County Jail.

A second man, also a Topekan in his late 20s and believed to be the gunman, fled the disabled car, Hadl said. A gun was not recovered. Police were still looking for him late Saturday. No description of the suspect was available.

Officers were not sure what caused the dispute, Hadl said.

The victims were a 38-year-old man who gave police an address at a Lawrence motel, and a 28-year-old woman from Olathe. They couldn’t be reached Saturday for comment.
