Wichita Police say a 24-year-old man was arrested Friday night after he fired a handgun at his sister and an acquaintance of her's.

Sgt. Joe Kennedy said it happened at 9:15 p.m. Friday at a mobile home park in the 500 block of east MacArthur.

Police contacted the sister, who said her brother was arguing with an acquaintance of her's, a 40-year-old man.

Kennedy said the sister and man tried to leave the scene in a car when the brother pulled a handgun and fired one shot at his sister and the man.

The victims were not injured.

Officers located the brother and transported him to the Sedgwick County Jail on two counts of aggravated assault.
