LENEXA, Kan. (AP) — A 20-year-old man is accused of endangering more than a dozen children and injuring three of them during a playground incident in the Kansas City suburb of Lenexa.

The Kansas City Star reports that Johnson County prosecutors charged Javon Locket of Lenexa with three counts of aggravated battery. Those charges allege he injured three children at a playground near his home Monday, leaving them with cuts, bruises and scratches.

Prosecutors also charged Locket with assault, obstructing legal process and 18 counts of child endangerment.

Police say officers responding to reports of an armed suspect throwing rocks at cars arrested Locket after a short foot chase.

Online court records don’t show whether Locket has an attorney to comment on his behalf.
