A taxi group in Londonderry has appealed for information after a young mother said she was raped by a bogus taxi driver
Laura Nixon, 22, who has waived her right to anonymity, said it happened in the city on Sunday morning.
Andrew McCartney from the North West Taxi Proprietors Association urged drivers with information to come forward.
He also said people needed to be careful when flagging down vehicles.
"If there is someone out there who is preying on vulnerable women, people need to be vigilant until this person is caught." he said.
Ms Nixon told her family she became concerned for her safety when the driver passed her home.
She said he locked the doors of the car and drove her to a lay-by near the Donegal border where the attack took place.
Mr McCarthy described the incident as "horrific" and urged the public to take precautionary measures to ensure they get home safely at night.
"I would encourage people to ring a taxi so you know the firm and who will be coming for you," he said
"The car should have a roof sign and there are things that make a car identifiable as a taxi.
"Be mindful and be careful when you are flagging down any vehicle, there are risks."
