A comic being chased by a pretend policeman was floored by a real Police Community Support Officer when a PR stunt spilled onto London's Oxford Street.
Lee Nelson - a creation of comedian Simon Brodkin - was chased around a store by the actor dressed as a policeman after "stealing" one of his own DVDs during a signing.
Shoppers looked on amazed and traffic came to a halt as the struggle took place on one of Britain's busiest shopping streets.
A spokeswoman for Brodkin said, "Somehow they ended up out on the pavement, where a real Police Community Support Officer got involved, thinking it was a theft taking place".
"Shoppers were looking on and buses were stopping, it was all very dramatic", she said.
"The Community Support Officer brought him back into the store where it was explained that it hadn't been a real theft taking place", the spokeswoman added.
Nelson said after his ordeal was over, "How can you get arrested for nicking your own DVD? Mr Loophole lawyer, if you're reading this, get me off and I'll sort you out with the 20 other DVDs I took".
