BAYTOWN, Texas -

A Baytown councilman is facing charges after police say he hit his ex-wife in the back.

Investigators said Mercedes Renteria's ex-wife was watching her son play a Little League baseball game at a field in the 1500 block of North 10th Street on Wednesday. Police said Renteria showed up at the game, walked up to her where she was seated in the bleachers, and punched her in the back.

Investigators said Renteria then began swearing at his ex-wife while witnesses looked on.

An off-duty Pasadena ISD police officer was coaching one of the teams and police said he tried to calm Renteria down.

Renteria has been charged with assault and disorderly conduct.
