WICHITA, Kan. (AP) — Three people have been robbed while walking in south Wichita.

The Wichita Eagle reports two 18-year-old men and a 19-year-old woman were walking along a street around 12:40 a.m. Sunday when they were approached from behind by three men. Wichita police Sgt. Brian Sigman said one of the men had what was “described as a machine gun.”

The suspects ordered the victims to get on the ground and stole a phone and wallet. Police say the three men then fled on bicycles.

Police do not have any suspects in custody.

Sigman said one of the 18-year-old victims was struck by one of the suspect’s weapons and received minor injuries. He was not transported to the hospital.
