Two British holidaymakers have been arrested on suspicion of raping a teenage tourist from the UK at their rented Costa del Sol villa.

Friends of the 19-year-old said to have been targeted raised the alarm after finding her unconscious in a bathroom at the property in Marbella.

The alleged sex attack is said to have occurred in the early hours of Sunday morning after a group of young female British holidaymakers met the men at a nightclub and agreed to go back to the villa they had rented for their holidays to continue partying.

The women found their friend 'naked and unconscious' in the bathroom around 1.30am on Sunday according to local reports.

She was taken to Marbella's Costa del Sol Hospital where she underwent a sexual assault forensic examination.
