PORT ST. LUCIE — A 15-year-old teen faces a charge of aggravated battery for shooting a BB gun at his mother’s backside.

The teen’s mother told police she and boy were arguing Wednesday afternoon when he cursed at her. In an effort to discipline him, the mother struck him twice in his arm, she and boy said. Then the boy shot her with the BB gun, he told police.

Neither the teen or his mother requested medical treatment.

Police said they have had to show up at the family’s home on Aires Lane several times in the past because the boy, who is on probation, is unruly and disrespects his family. Earlier that afternoon, the teen punched a flat-screen television during an earlier argument, the mother said.

The boy was arrested on a second-degree felony charge.
