The youngsters were forced to flee in the middle of the night after one was groped on the beach while another had to push off a staff member who tried to assault them.
The British travellers said they were shocked that the staff member allegedly involved in the assault was still at the hotel the next day.
After they complained to the Turkish police and lastminute.com, who they booked the trip through, hotel staff claimed the group of teens – three females and one male – had been “drinking” and “looking for group sex”.
But the group, from Surrey, has hit back, with the mum of one of the girls in the group saying they had been advised by the British Embassy to immediately leave the area as it was known for sexual assaults on Westeners.
The mother told The Sun Online: “They’ve been out there on their first holiday away together as friends abroad, and for this to happen to them is just heartbreaking.
“It has been so stressful for all the parents back home too because we want to help them but we couldn’t.”
One of the 19-year-old girls claimed she was sexually assaulted by a staff member at the Savk Hotel in Alanya, a resort town on Turkey’s Mediterranean coast, on the third night of the holiday.
The group immediately flagged their concerns with the hotel but said the reception staff simply laughed at them – with the staff member involved continuing to work there.
