Wild parties organised on Facebook could be banned in Germany after a series of gatherings advertised on the website descended into violence.
Authorities have called for parties promoted on the social networking site to be prohibited in advance if police believe they pose a threat to law and order.
Last month 100 Hamburg police offers made 11 arrests when 1,600 people gatecrashed a 16-year-old girl’s birthday.
The girl, who had to flee the party, had apparently forgotten switch on her Facebook privacy settings when inviting friends to the celebration.
Later in the same month in the town of Wuppertal police arrested 41 partygoers and 16 people were injured when 800 users of the social networking site caused havoc at another party.
