A 22-year-old Lawrence man was arrested on a charge of aggravated assault Wednesday afternoon the Community Building, 115 W. 11th St., after an alleged altercation with a 28-year-old man over a basketball game there.

Sgt. Matt Sarna, a Lawrence police spokesman, said the suspect was accused of retrieving a handgun from his bag and showing it to the 28-year-old man. The suspect then left the building, but police were called and arrested him in the parking lot on charges of aggravated assault and defacing a firearm.

Police did recover a gun, Sarna said. Jail records also list a charge of possession of a stimulant, but prosecutors are expected to make a decision about formal charges Thursday. The Journal-World generally does not name suspects until they are formally charged.
