This is the moment a customer was knocked over by a loose truck rolling into a shop in Thailand.

Atchara Inklab, 29, was having her motorcycle repaired when the ghost tyre barreled into the garage in Samut Prakan province, on February 20.

CCTV footage shows the rubber wheel hitting the woman from behind. She was propelled forward, causing her to hit hear head on a motorcycle. A mechanic, Wasan Wankhao, 18, was also struck on his left side, leaving a large bruise near his ribcage.

Medics later arrived at the scene to administer first aid to Atchara, who was bleeding from her head.

She said: 'I had just finished work and was having my motorcycle chain adjusted. While I was standing with my back to the road, the truck wheel suddenly came out of nowhere and hit the back of my head. I fell and also hit my head on the ground. I was scared because I was bleeding so much.'

A police spokesman added: 'We believe the tyre probably fell from a passing vehicle in the area. It may have been dislodged because the road surface is uneven. However, we will check the CCTV footage to see which car the wheel fell from so we can take legal action.'
