Truck tosser had crap in cop car

A MAN is facing jail after driving his truck around a beauty spot while naked and masturbating furiously.

Mark Denham, 52, was arrested after a witness called cops to report that a naked man was wanking in a red pickup truck.

An officer found Denham wearing nothing but a pair of brown sandals.

Cops used a towel they found in the truck to cover his genitals as they walked him to a squad car in Wausau, Wisconsin, where Denham promptly shat himself.

Denham, who has no known address, was charged with lewd and lascivious behaviour and disorderly conduct.
