Swiss Islamic scholar Tariq Ramadan has been accused of rape and sexual assault by three women. Ramadan, a professor at the University of Oxford, denies any wrongdoing.
Le Monde and Le Parisien newspapers reported at the weekend that a woman had filed a complaint on Friday against Ramadan, 55, for an alleged rape in 2009. Another woman had alleged on October 20 she was also assaulted by Ramadan in 2012.
Paris prosecutors said they had opened a rape and sexual assault investigation against Ramadan following the first complaint. Ramadan's lawyer, Yassine Bouzrou, has denied the accusations and says his client is suing for "slanderous allegations".
