A dispersal zone to protect young music fans will be rolled out around Wembley Stadium for the second time this month.

Police are bringing in the measures as thousands of screaming and singing teenage girls will flock to the venue for Capital Summer Time Ball concert which takes place tomorrow.

The annual event hosted by Capital FM includes live performances by Pharrell Williams, Miley Cyrus, Cheryl Cole and Rita Ora.

Starting at 12.01am tomorrow the 24-hour measure will allow police and PCSOs to order suspicious groups of two or more to leave the area.

If they refuse to leave or return within 24 hours they can be arrested and hauled before the courts where they can be fined a maximum of £2,500 or jailed for up to three months.

An identical order was rolled out for three days at the beginning of the month to protect fans of boyband One Direction.

Chief Superintendent Michael Gallagher, Brent Police borough commander, said: “This is a proactive police tactic in order to help us effectively police the event and to minimise any crime and anti social behaviour around the stadium and in local streets.

“We will not tolerate people coming to Wembley with the intent of committing crime and antisocial behaviour and spoiling the day for genuine law abiding fans and local residents.

“We will use this power proportionately to disrupt their unlawful activities and send a message that they are not welcome on Brent.”
