Wichita ? Wichita police say a woman is recovering after being injured in a strange shooting.

Police say the 19-year-old was shot in the chest Monday when her boyfriend began taking off his shorts as they walked along a city street.

Lt. Randy Reynolds say a gun the 18-year-old boyfriend was carrying in waistband fell to the ground and fired, hitting the woman.

Reynolds says the Wichita man first told police a car had driven by and fired shots at the couple, but later changed his story.

The man was arrested. Police did not say why he was taking off his shorts on a city street.

The Wichita Eagle reports that the woman is hospitalized but her wounds are not life-threatening.
