Judge Zakaria Abdel-Aziz, the general attorney for Cairo appeals prosecution, ordered Saturday the summons of belly dancer Sama El-Masry on charges of "spreading obscenity" in Egyptian society.
The complaint was filed by Mortada Mansour, the controversial lawyer who had announced he would run for Egypt's presidency before backtracking last week.
Mansour also accused El-Masry — who has been under the spotlight since she began releasing amateur videos mocking Islamists during the rule of president Mohamed Morsi — of libel and defamation.
The complaints come after El-Masry and Mansour exchanged crude allegations and threats in online videos and televised interviews.
The investigation with El-Masry will begin Tuesday, reported Al-Ahram Arabic news website.
El-Masry was briefly detained last Sunday on charges of operating satellite channel Feloul without a license.
She was fined LE10,000 in court verdict that also ordered the confiscation of broadcasting equipment used for the channel.
Feloul, an Arabic word used since the 2011 uprising to refer to supporters of or figures in the old regime, was launched in January.
