Police and council bosses say they have scuppered plans for a huge unauthorised beach party on North Tyneside.
It was feared up to 1,000 people would gather on Saturday at Tynemouth's King Edward's Bay after registering on a social networking site.
But North Tyneside Council and Northumbria Police obtained an injunction blocking the event on the grounds of public safety.
Police pledged to increase patrols to prevent large unauthorised gatherings.
Ch Insp David Felton, of Northumbria Police, said: "Public safety is of paramount importance to us.
"We fully back the injunction to stop this event going ahead, which we feel would have a negative impact on the local community.
"Officers will be on patrol in this area to monitor the situation and will use all necessary powers to prevent any potential breach of this injunction."
North Tyneside elected mayor Linda Arkley added: "Our beaches are a great asset and we want them to be places that people of all ages can relax and enjoy as safely as possible.
"We had very real concerns that this large-scale event was not properly organised and could have put at risk the safety of those attending, particularly with it being at a coastal area."
The injunction, under section 222 of the Local Government Act 1972, forbids the organisation of a beach party at King Edward's Bay or any other beaches owned and controlled by the council without proper approval.
