Griveaux, 42, a former government spokesman, pulled out of the running for Paris mayor after the scandal broke. Show Hide The year-old Russian conceptual artist fled to France in after being detained and questioned over sexual assault allegations made by a female actor. De Taddeo is believed to have been the recipient of the video and messages, which were uploaded on to a website created by Pavlensky and widely shared on social media. A St Petersburg native and art school graduate, he gained fame after the trial of the punk protest group Pussy Riot, which he said convinced him of the need for a radical turn in art. In his adopted country, he set fire to a Bank of France office and has supported the gilets jaunes protest movement. He denies the allegations, claiming they were politically motivated. Pavlensky, 35, and De Taddeo, 29, were taken into custody on Saturday and questioned for two days. When he was arrested for setting fire to the doors of the headquarters of the FSB security service, he incorporated his arrest and trial into his art. Prosecutors requested on Tuesday that he be placed in detention over that incident.
