A pervert is frogmarched naked into a police truck after being caught having sex - with a COW.

The 40-year-old man was spotted by horrified villagers kissing then mounting the cattle from behind at 9.30am in Lampang, Thailand.

They chased him and he fled naked into the bathroom of a nearby farm - barricading himself inside as furious locals tried to get him out.

Officers arrived 30 minutes later and handcuffed him, before hauling him naked into a police truck where he LAUGHED about his depraved act.

The man told police he ‘’felt the urge’’ to have sex with the cow and began fondling her backside and udders before ‘’having sex until he orgasmed’’.

He said he felt ‘’strong emotions’’ and could not stop himself from feeling attracted to it as he watched it grazing. Locals later gave him a pair of blue shorts to cover himself up with.

Officers checked the cow and found traces of the man’s semen around her vagina and saw her fluids on the man’s groin. He was arrested after admitting having sex with the cow and taken to the station to be charged with depravity.

Farmer Tong Kai Charoonprasitporn, 65, who owns the cow, said: ‘’I saw the man snogging and groping and f****** my cow. We chased him but he did not stop. We called the police and found him hiding in the bathroom of the house. If we didn't catch him might he have carried on with the other cows. it is sad that the animals are not safe because of one person.''

The brown cow was unhurt and carried on grazing afterwards. The man was charged and released with a fine.
