For the third time this week, police had to move in to end an illegal party in Paris. 

Hundreds of young people gathered in front of the Army Museum for the 'Project X' party on Saturday. 

It was the third party on the site since Thursday. The parties were organized on social media and are named after a 2012 American movie.

Police detained three people after Saturday's event, which came after the evening curfew time was moved back to 11 p.m. local time from 9 p.m..
