A 57-year-old Lawrence man was arrested at his home Friday night on suspicion of aggravated assault.

Sgt. Ted Bordman of the Lawrence Police Department said the victim flagged down a patrol car about 11:40 p.m. and told officers the man had threatened him with a gun during a dispute.

When officers knocked on the man’s door in the 1300 block of Kentucky Street, he answered it with a .357 magnum revolver in his hand. Police arrested him and found a second pistol on the premises, Bordman said, before taking him to jail.

Bond has not yet been set.
