This is the hilarious moment a cheeky wild monkey slipped its hand inside a British woman's shorts.

Footage shows the primate walking up to the friendly tourist Lou Torz while she was taking pictures along the mountain road in Phuket, Thailand.

It lifted her shorts then reached a hand up and felt around - possibly looking for food - before walking around to her backside and yanking down her garment.

Lou's partner, who was watching the incident unfold was heard saying 'is he trying to touch your... what the hell, you've pulled'.

Amused Lou jokingly told the monkey 'at least buy me a drink'.

Speaking after, Lou, a tattoo artist from Halifax, West Yorkshire, said: ‘It was one of the most unforgettable experiences I have in that island. The monkey was so naughty.'
