CCTV footage shows the moment a Swiss tourist was punched in the head - after he turned off a man’s moped.

Andreas Lechner, 55, sat down at a street food stall to eat grilled chicken in the early hours of Sunday morning in Pattaya, Thailand.

But he was annoyed by the motorcycle's ‘’noisy’' engine running because it was disturbing him as he tried to eat after a night partying. He walked over and flicked the keys in the ignition to cut the power then returned to sitting on a bench to eat his food.

But the motorcyclist Sing Saeung, 54, reacted angrily and stormed towards the holidaymaker - wacking him round the head. Andreas was later filmed covered in blood with his head bandaged up as he recounted the attack.

He said: ‘’I was eating my food and was irritated by the motorcycle. It was noisy and nobody was attending to it.

‘’I walked over and turned off the engine and sat back down. Then from behind somebody came and hit me on the head. I was bleeding a lot but was given help by people in the street. I don’t think I did anything wrong, just turned off the motorbike because it was loud.''

The scooter rider was later arrested by police and admitted punching the tourist in the head. He was taken back to the scene of the attack and re-enacted it with Andreas sitting on a bench.

Lt. Col. Piyapong Ennawat said: ‘’Mr Saeung has confessed that he was angry his motorcycle was turned off. He returned to the street and demonstrated what happened. Mr Lechner also watched. The offender has admitted the attack and will be dealt with quickly according to the law.''
