A Thai 'caveman' had his bizarre hovel probed by police after he boasted of bedding dozens of foreign backpackers.

Chatupoom Losiri, 47, moved to the beach cave three years and began seducing attractive holidaymakers on the Full Moon Party island of Koh Phangan, Thailand.

But he caused uproar earlier this month and posting a picture of a stunning young Russian woman he claimed to have chatted up outside a grocery shop before she nervously climbed on his motorcycle and went back to his grotty dwelling.

He told her: ''I was riding home but had to stop because of your beauty, I need to know if you’re beautiful on the inside as well.”

A few days later, Chatupoom then posted a picture of a different young western woman sleeping naked on his filthy bed after they had spent the night together.

Chatupoom – who calls himself the Thai Cave Man and uses the persona to pick up women – wrote that he was ''very tired'' from the previous evening but still woke up to ''drink coffee and meditate'' while the naked woman slept.

The cave man's antics sparked outrage from locals who accused him of showing a lack of decency after dozens more images emerged of women he had taken back to his cave.

Police arrived at the cave, a former tin mine, and searched for anything suspicious but found nothing.

They admitted that Chatupoom had not broken the law but said they would monitor the situation.

Speaking to reporters, Chatupoom denied that he had done anything wrong and said that all of the women who visited his cave were there of their own choice.
