Tennis fans have been arrested for carrying "picnic" knives into the Wimbledon Championships.

A Met police spokesman confirmed that a 66-year-old man was also arrested and cautioned for being in possession of CS Spray yesterday.

On Wednesday a 61-year-old man and a woman, 30, were stopped for carrying the knives and were both given cautions.

And yesterday a 22-year-old woman, 14-boy-year-old boy and 42-year-old man were all arrested for carrying knives.

Officers did not proceed with any action against the woman, reprimanded the boy and cautioned the man, said the spokesman.

He said most of the blades in question were classed as lock knives.
