(CNN) UK authorities plan to raise concerns with Cyprus over a trial that saw a British teenager found guilty of lying to police after she alleged she was gang raped at a resort.

The 19-year-old, who cannot be named for legal reasons, had said she was attacked by 12 Israeli youths on July 17 at the Pambos Napa Rocks hotel in the resort of Ayia Napa, where she was staying.

But 10 days later she retracted her statement and police arrested her. She was found guilty of causing public mischief on Monday and now faces up to a year in jail.

"The UK is seriously concerned about the fair trial guarantees in this deeply distressing case and we will be raising the issue with the Cypriot authorities," the UK's Foreign and Commonwealth Office said in a statement.

The woman spent more than a month in prison before being granted bail. Her passport has been held to prevent her leaving the country.
