Police arrested a 21-year-old Lawrence man in connection with an early-morning assault and battery outside of Burrito King, 900 Ill.

An incident there began when one vehicle hit another in the drive-through lane, said Lawrence Police Sgt. Michael McLaren. The occupants of the vehicle that was bumped got out of the car and approached the other driver. The driver of the second vehicle, a 21-year-old Lawrence man, got out of the car and punched a 21-year-old male, a student at Kansas University, knocking him to the ground. The suspect then removed a handgun from his waistband and struck a 19-year-old woman, also a student at KU.

The suspect fired one round into the air near the victims, then fled the scene. The suspect was later arrested Sunday evening in the 700 block of Crestline Drive.

Sgt. Mark Warren said the suspect was identified based on information received early this morning.

“He’s somebody we’ve dealt with before,” he said. “We had some addresses we were watching and happened to see him.”

He was booked into jail at 7:23 p.m. Sunday, accused of aggravated battery and two counts of aggravated assault. Bond was not set.
