SEDGWICK COUNTY—Law enforcement authorities are investigating a robbery that allegedly occurred during the sale of shoes via an online app.

Just after 1p.m. Monday, police responded to report of an aggravated robbery at a home in the 1600 Block of North Emporia in Wichita, according to officer Charley Davidson.

A 19-year-old man told police he was selling a pair of shoes on the OfferUp app.  Two unknown men described as in their 20s or early 30s arrived at the home in a grey Chevy Impala.

During the transaction, one of the suspects pointed a gun at the teen victim. During a struggle, the victim was shot one time in the shoulder, according to Davidson.  The teen was transported to a local hospital for treatment and has been released, according to Davidson.

Investigators have developed two potential suspects in the case. They are working to locate them.

Davidson released no additional details on Tuesday.
