ARANSAS PASS, Texas — A South Texas police officer had to deal with some unexpected monkey business as he wrote a speeding ticket.

A pet monkey bit Aransas (uh-RAN'-zuhs) Pass Officer Keith Moore on the hand in an attack captured on videotape.

KRIS-TV in Corpus Christi reported Thursday (http://bit.ly/14b9fO0) that Moore had a video camera on his glasses during the traffic stop.

Moore is seen handing the driver something to sign when a monkey leaps from the back seat, bares its teeth and bites the officer's right hand.

Moore says the monkey "came out of nowhere" during Wednesday's incident. The bite left a mark, but the 21-year-old officer was not hurt otherwise.

The trained monkey makes appearances at carnivals and other entertainment events.
