Prosecutors have ordered the detention of six men for four days pending investigations into allegations of sexual assault in Tahrir Square, Aswat Masriya reported.
Security forces arrested seven suspects after mass sexual assaults occurred during celebrations on Sunday for the inauguration of Egypt's new president, Abdel-Fattah El-Sisi.
A YouTube video emerged on Monday showing a woman being stripped of her clothes and attacked by a number of men in Tahrir Square.
Several accounts of sexual assault in the iconic square were reported on Sunday night across news websites and satellite channels such as Tahrir and Hayat.
The square was closed off by security forces in the early hours of Monday morning, reportedly due to the sexual assaults and fights between street vendors.
Another three sexual harassment suspects were detained on Monday pending further investigations.
A recent law – the first of its kind – against sexual harassment was passed last week by former interim president Adly Mansour. It imposes stiff punishments on sexual harassers, including a minimum of six months in prison and hefty fines.
Sexual harassment against women is a rampant problem in Egypt. A United Nations survey from last year suggests that over 99 percent of Egyptian women have suffered some form of sexual harassment, from minor incidents to rape.
