Detectives are to speak to Sir Paul McCartney.

It follows a fracas which took place when he went to see David Blaine's glass box stunt in September.

Officers will speak to Sir Paul as a matter of routine before deciding whether to pursue the matter further.

Their inquiries concern an alleged scuffle with a photographer.

The former Beatle was upset after the photographer tried to take a picture of him.

Kevin Wheal, who was working for London's Evening Standard newspaper, claimed Sir Paul pushed him in the chest.

When it emerged long-standing publicist Geoff Baker had tipped off the photographer Sir Paul fired him but later dismissed the sacking as a joke.
