Detectives are appealing for a woman who was sexually assaulted in a hotel room in Kavos to come forward.
Essex Police were contacted on August 16 and handed a video of a young woman being sexually assaulted on a bed during the early hours of July 30.
Senior Investigating Officer, DI Hayley King, said: "We don’t know when the young woman returned to the UK or which airport she flew back into.
“We strongly believe that she is from the UK.
“The offence took place in a hotel room.
“We don’t know which hotel it is in Kavos, and there are many.”
In a bid to help the young girl identify herself, police have revealed that she wore a number of coloured wristbands which she obtained from local clubs.
Anyone with information in connection with this sexual assault investigation is urged to contact Essex Police’s Sexual Offences Investigation Team in Brentwood on 01279 625428 or email firstname.lastname@example.org.
