A cab office worker has spoken out for the first time in 20 years about taxi drivers abusing underage girls in West Yorkshire, in light of the Rotherham child abuse scandal.
"Zayn" - not his real name - said girls as young a 14 would be taken to locations including parks and side streets and sexually assaulted by up to three men at a time.
He said the majority of the girls were from the Pakistani community.
He told the BBC's Asian Network the memories "haunt me to this day" and said he regretted not speaking out sooner.
