A FEMALE tourist has sparked anger after she stripped naked and rubbed herself against a mythical rock shaped like a penis.

The blonde woman was seen pulling down her hot pants next to the Hin Ta - or Grandfather Rock - on holiday island Koh Samui, Thailand.

She was then snapped thrusting herself against the 12ft-high sacred rock - which locals believe holds the spirit of an old man.

Furious residents are now demanding cops find the woman and force her to publicly apologise for the incident, which happened on March 12.

Food seller Sutida Wongyai said: ''The rock is very special and represents our island.

"It is an insult to do this to it.''

Hotel boss Suriya Promsri added: ''Nobody should be naked in public here. That's offensive.

"The police need to find her and prosecute her. It will warn other people not to disrespect the island.''

Resident Niwin Suksan, 34, who runs a stall near the stone, added: ''I felt very uncomfortable after seeing the picture.

"I want the police to take appropriate action to avoid this happening again.

"The grandfather rock has a long history and the people of Samui are proud of it.''

The Hin Ta rock, a major tourist attraction in the island, is found next to a smaller Hin Yai rock.

The first is said to resemble male genitalia and the second female.

Locals believe an elderly couple sailed to the island to propose a marriage for their son but their boat was capsized in a storm causing them to lose their dowry.

Fearing the shame of turning up penniless, they are said to have jumped into the sea before being reborn as two male and female rocks on the island.

Despite warning signs on the beach, the phallic shape of the rock regularly attracts pranksters who cause offence by climbing on it or posing next to it.

In August 2016 local authorities launched an unsuccessful manhunt for a tourist who went rock climbing on rock the posing on top of it.

And in February a model sparked anger with a cheeky photo in front of the landmark.

Police on the island confirmed they had received a complaint about the naked tourist and were investigating.

A spokesman said: ''This is not acceptable and officers will investigate the images and try to find the woman.''
