This is the shocking moment a brazen monkey stole milk from the back of a pickup truck at traffic lights.

The primate was spotted hopping onto the vehicle in search of food but was shooed away by a woman sitting on it in Roi Et, Thailand, on October 6.

Footage shows the animal jumping into another white truck and grabbing a plastic bag. It then immediately opened the bag and took the beverage out. Upon seeing this, the driver stepped out of the vehicle to retrieve the item that had fallen to the ground as the monkey ran away.

The filmer said that monkeys have been causing a rising number of problems in the neighbourhood. He said they often take items from cars and even barge into homes in search of food.
