TEN sailors are facing the axe from the Navy after performing sickening sex acts in a country pub in front of stunned boozers, reports claim.

A probe has been launched by military and civilian police after the sailors filmed themselves carrying out the lewd acts before posting them on Instagram.

The personnel from 820 Royal Naval Air Squadron had been drinking in the Red Lion Pub in Helston, Cornwall, on February 4 when the incident unfolded, Mail on Sunday reports.

Landlady Hayley Nicholas told the newspaper their behaviour was "disgusting and completely unacceptable" and claimed they ignored their pleas to calm their behaviour down.

The sailors could now be booted out the Armed Forces - with at least one removed from operational duties at Royal Naval Air Station Culdrose in Cornwall pending the investigation outcome.

Ms Nicholas said: "They should face action for what they did. It might be their idea of a joke but it was appalling in a public place.

"They’ve made a big mistake. Their actions were recorded on the pub’s CCTV cameras and the tapes are now being reviewed by military police.

"We tried putting a stop to it when we saw one of the men take his trousers down but they didn’t take any notice of us."

According to the newspaper, the Royal Military Police’s incident report describes how the sailors were "rowdy and disruptive".

The report also describes the indecency in a public place and "several other incidents" after the group's antics in the pool room of the pub.

It says: "CCTV footage taken within the Red Lion pub in Helston shows a Petty Officer [Identity Redacted] appearing to engage in an indecent act while in the bar lounge and in full view of the public and other Service Personnel (SP), some of whom were filming the incident on their mobile phones."

A spokesperson for Devon and Cornwall Police said: "We have been informed by the Navy police of allegations related to an incident of public indecency. We will be liaising with them in an investigation."

A Royal Navy spokesman added: "An investigation is ongoing and therefore it would be inappropriate to comment further."
