Police on motorbikes and horses evacuated the Vondel Park in Amsterdam on Friday night following what is believed to be a massive fight involving around 60 people, according to media reports.

By around 23.00 hours there were hundreds of messages on Twitter reporting the evacuation of the park with some reports saying that a policeman had been hit and others claiming many arrests had been made.
The cause of the fight was unclear but the atmosphere in the park was ‘grim’ said one eye witness.
The warm weather meant that the park was extremely crowded.
