Hundreds of wild monkeys climbed on people's heads at a festival in Thailand.

The annual event has become known as the 'monkey birthday party', 'monkey picnic' or 'monkey buffet'. It is held in Lopburi, which has a large population of wild monkeys that roam freely through the town centre.

Many congregate around an ancient Buddhist temple but they have also taken over a cinema - forcing the previous owner to move out and close the business.

The area has become notorious for monkeys climbing on cars, invading homes and shops, stealing food and even attacking people.

Residents believe that the monkeys bring good luck to the town and they treat them with food, which is seen as a good deed in the Buddhist religion, which is prevalent throughout Thailand.
