Cumbria Police have issued a warning to social media users after around 400 people turned up to a 15th birthday party in Egremont.
Police believe that the uninvited youths turned up after seeing the party publicised on a social media site.
Officers were called to Market Hall in Egremont at around 7pm on Saturday night (11th May), after reports that a large group of youths were drinking in the street and causing a disturbance.
The party organisers had expected around 150 guests to attend.
Police spent several hours dealing with the incident, with some youngsters throwing bottles at passing cars.
A large amount of alcohol was recovered from people who were aged under the age of 18, and many had to be taken home as they were in a "drunk and incapable state."
“A lot of young people see binge drinking as socially acceptable and don’t fully realise the consequences of what they are doing or the impact it has on their communities.
“They don’t realise that when they put something onto social media, it can be advertising it to everyone.
"We encourage people to check their security settings and make sure friends and family are only seeing their posts. Be aware when putting details of parties on, don’t give out all of the information.
– Inspector Mark Wear, Cumbria Police
“Egremont was recently involved in a very successful dispersal order, where activities had been organised to encourage young people to become involved in something worthwhile.
"This incident highlights the responsibility we all have in making sure our children are safe.”
