The Saturday referral comes less than a week after a mob brutally attacked and sexually assaulted a group of women during celebrations following the inauguration of President Abdel Fattah el-Sissi.
The speedy trial reflects a government push to address the issue. Harassment has long been a problem, but assaults have become more frequent and gruesome over the past three years.
El-Sissi visited one of the survivors in the hospital, apologising and promising tough actions against the attackers.
