The taxi driver acquitted of raping a drunk female passenger claims cab drivers are frequently offered sexual favours as payment.

Prabhjit Gill, 37, said he knew of up to 60 drivers who had been offered sex, and said he was personally offered oral sex as payment for fares "two or three times" a month.

Mr Gill said he never accepted sexual favours as payment, but knew of many cab drivers who did.

Mr Gill, who was cleared by a Perth District Court jury yesterday of raping a 25-year-old passenger, said the practice was commonplace in the taxi industry and it was openly spoken about between drivers.

"You drive, you pick up a girl, and they have no money. They offer you [oral sex]."
