Police were called to a nudist beach in France after a group of clothed teens reportedly started causing trouble.
A group of around 10 fully-clothed teens visited the beach at Le Teste-de-Buch in Arcachon on Friday.

But, instead of getting naked like the other bathers, they "acted provocatively", staring at the women in what is well known to be a breach of France's nude beach etiquette.
According to The Local, the behaviour prompted other nudists to step in, telling the group to "get nude or get lost".
The Metro reports that there was shouting and punches were thrown.
Two people who tried to flee the scene were arrested but later released.
Police are still investigating the incident.
