A member of a radical feminist group performed a fake suicide in Notre Dame cathedral in Paris, the day after a conservative historian shot himself at the altar of the 850-year-old monument, according to the Guardian.
The group, named Femen, is famous for its topless protests and radical demonstrations.
Wednesday, a member reportedly named Marguerite stood in the church with a handgun in her open mouth. She had "May fascism rest in hell," written in black lettering across her bare chest.
Cathedral guards took the woman aside, away from the crowds. They detained her until she was arrested by police outside Notre Dame and driven to a police station nearby.
On its Facebook page, Femen took full responsibility for the demonstration.
"Femen appealed for the death of fascism at the exact same place extreme-right activist Dominique Venner committed suicide yesterday afternoon," they wrote. "Our activist was arrested by the police."
Leader of the Femen group Inna Schevchenko told the press that French conservative politician Marine Le Pen was one of the targets of the protest.
"It is a message addressed to all those who support fascism and those who have expressed sympathy for the extreme-right militant who killed himself in Notre Dame," she said. "Namely, Marine Le Pen."
Le Pen, who ran for French president alongside current leader Francois Hollande and former president Nicolas Sarkozy, took to Twitter after the 78-year-old man placed a note on the altar, shot himself and died in Notre Dame.
She wrote of her "respect" for the man, saying his death was an "eminently political" demonstration.
The deceased, identified as Dominique Venner, was a radically right-wing historian who often posted controversial blogs on his website. In his final blog post, he chided the government for passing legislation allowing same-sex marriages.
He also sent a note to loved ones before killing himself that detailed the motives behind his suicide.
"I expect nothing more from life except the continuation of my race and my spirit," he wrote. "However, at this, in the evening of that life and in the face of immense dangers for my French and European heritage, I feel the need to act, while I still have the force."
Venner also wrote that he decided to commit suicide in Notre Dame, for its "symbolic" nature. To him, it was a "place...which recalls our immortal origins."
