Two 29-year-old women were taken into police custody after whipping off their tops in the middle of Crescent St. Thursday to protest the exploitation of women.

The two women were arrested after a struggle and now face charges of indecent exposure, disturbing the peace and public mischief. One was released but the other was detained Thursday night, as she faced an additional charge of breach of conditions.

Both women had slogans written over their torsos reading 'Femen,' 'Slavery is not a choice,' and 'My body is not your business.'

They also yelled repeatedly that "Montreal is not a brothel" while one of the pair opened a bottle of what appeared to be champagne and sprayed the contents.

Security guards promptly moved in to take the pair to an alleyway where police soon arrived. One woman had to be dragged off one of the Formula One race cars that was on display.

The two women remained in police custody several hours later as they waited to be interviewed by an investigator. Police said that they would likely be charged with mischief.

Brian Fogt, the president of BBF Promotions which runs the Crescent St. Grand Prix activities, was visibly upset by the protesters and was recorded telling them to "get the fuck out of here now." The protesters then screamed back "fuck your morals."

This week aid workers said the Grand Prix routinely brings an increase in sexual exploitation and abuse to the Montreal area, especially from tourists who will be long-gone before they can be tracked down by police. 

One of the protesters is Neda Topaloski, a Femen activist who has disrobed twice in recent months in the National Assembly and in the House of Commons.

In April Topaloski infiltrated the National Assembly by posing as a journalist. She then interrupted a news conference by Culture Minister Helene David to repeatedly scream "No to Bill 20" and oppose any restriction in access to abortions.

Earlier this year Topaloski was removed from the House of Commons after exposing her breasts in a protest against Bill C-51.

Last year Femen targeted a speech by Philippe Couillard in April, as well as one by Pauline Marois at around the same time.
