A monk has allegedly been filmed watching loud porn on his smartphone on public transport in broad daylight.

The young man in orange robes and sunglasses is seen resting his phone against the chair in front of him while he watches a man and woman who appear to be having sex.

It was captured by student Wittawat Wonghajuk, 19, who had been travelling on the coach at 10am on Saturday morning in Loei province, northern Thailand.

He uploaded the video to Facebook with the caption 'Help me share this clip. I can’t stand it' and it has now had more than 1.5million views.

The clip has proven controversial with some commenters saying the scene was staged.

Mr Wonghajuk claims he overheard the monk watching the film after he put the clip 'on the speaker'.

He begins filming but after around 30 seconds the man turns around and quickly turns off his phone.

Mr Wonghajuk said: 'As soon as I turned to see, I could see the porno clip. Two people were naked having sex.'

The student, who is studying music, said he usually enjoys the journey home to Nong Bua Lamphu province but he is outraged at the man's brazen behaviour in front of other passengers.

'I wanted to confront him but I didn't have the courage to do that. This is a monk and I'm just a young student,' he said. 'But I filmed it instead so I have proof. The monk left the bus at the Wang Sapung district.

'I wanted to show people so they can see what happened.'

Monks are highly-revered in Thailand and Mr Wonghajuk's footage sparked a backlash from commenters online.

Earlier this month a woman, who was slapped by a monk after she confronted him for apparently spitting inside her minivan, was fined 5,000THB (£112) for 'causing a fight'.
