Police reinforcements have been called in to ensure DJ Fatboy Slim's Brighton beach gig on Saturday is trouble-free.

More than 60,000 people, 15,000 more than last year, are expected to attend the show, dubbed Normstock II.

Europe's largest free beach party has been the subject of months of planning by a safety advisory group (Sag) comprising Brighton and Hove City Council, emergency services and the promoters.

Chief Inspector Kul Verma, of Brighton and Hove police, said: "The threat of problems has been assessed and sufficient numbers of officers will be deployed."

A local police support team, equipped with shields and protective clothing, will be on standby to deal with any disorder but Mr Verma said: "We are hoping they will not be needed and the event is a peaceful and successful family occasion."

Roads are expected to be congested and people are urged to use public transport.

A fireworks display will mark the end of the concert and Kings Road will be closed to traffic 15 minutes beforehand to allow pedestrians to leave the beach safely.

Stairwells to and from the Lower Esplanade will be made one-way to avoid pedestrian congestion.

All pubs, clubs and other licensed premises in the seafront and city-centre area have been asked not to serve drinks in glasses.

Mr Verma urged members of the public to act sensibly.

He said: "Don't take glass on to the beach, don't drink to excess, act responsibly and enjoy yourselves."

Council chief executive David Panter and city police commander Chief Superintendent Doug Rattray have been heading monthly Sag meetings to determine arrangements.

Mr Verma has also been giving briefings to Fatboy Slim, whose real name is Norman Cook.

He said: "Meeting Norman has been very exciting for me - I am a fan and am looking forward very much to the event."

More than 200 stewards will be on duty and the council's patrol boat will circle just off the beach to ensure people do not get into trouble in the water.

The beach will be floodlit and the seafront road is expected to close as crowds grow.

Thousands more people will be able to watch the event live on TV on the channel E4.

The event is part of the council's where else campaign for Brighton and Hove to be named City of Culture 2008.

A spokesman said: "It is a lot of work for our events team and people from the environmental departments but we think it is well worth it.

"It costs taxpayers virtually nothing, gives tens of thousands of people a great show for free and pubs get hundreds of thousands of pounds of business."

An army of council staff will spring into action as soon as the gig finishes to clean up.

Norman Cook is meeting estimated costs of £200,000 to £250,000.
