Prince William leaving Boujis Nightclub in Kensington and driven to Clarence House. London, England - 04.10.07

William's spokesman Paddy Harverson said it was "incomprehensible" that the Prince and his on-off girlfriend Kate Middleton were pursued by photographers as they were driven away from Boujis nightclub in South Kensington, London on Thursday (4Oct07).

The spokesperson says, "Prince William was concerned by the threatening behaviour of the paparazzi in London last night (Thursday).

"Having already been photographed leaving the club, he and Kate were then pursued in his car by photographers on motorcycles, in vehicles and on foot.

"The aggressive pursuit was potentially dangerous and worrying for them. It seems incomprehensible, particularly at this time, that this behaviour is still going on."

Diana died in car crash after she was allegedly pursued by paparazzi in 1997.
