POLICE are investigating a sex attack on a 17-year-old girl by a taxi driver.

The girl was indecently assaulted by the driver who was taking her home after a night out with friends in Watford.

Officers say that after picking up the teenager and a friend in Watford, the taxi driver drove back to St Albans, dropping the friend off in Fleetville, before taking her to her home in Colney Heath.

When they arrived, the driver locked the doors and turned to the girl and, after asking her for payment, asked if she wanted anything else.

He then leaned across and put his hand on her knee and moved his hand underneath her dress and between her legs. He then asked her if she was sure she did not want anything, before allowing her to get out of the taxi.

The driver is described as Asian, 35, short, and of tubby build. He was unshaven and spoke with a thick Asian accent.

Anyone with any information is asked to call 01727 796002.
