A wild elephant in Thailand has been caught on camera as it rammed a car in Khao Yai National Park near the capital, Bangkok.

The weekend attack was followed on Monday by another on a shop and a restaurant in the park.

Officials said it was not clear whether it was the same elephant.

Park chief Kanchit Srinoppawan said the aggressive behaviour was the result of the mating season.

No-one was injured in the incidents.
