CAIRO, May 14 (Aswat Masriya) -  Political activist Sanaa Seif turned herself in on Saturday to the Sayeda Zaynab prosecution to spend six months in jail for insulting the judiciary, lawyer and member of the Front to Defend Protesters Sameh Samir said.

Samir told Aswat Masriya that a lawyer was present with Seif as she turned herself in, so as to take all legal procedures necessary for the sentence.

The Sayeda Zaynab court tried the activist in absentia last Wednesday and sentenced her to six months in prison on May 4.

A security source told Aswat Masriya that Seif did not demand an appeal to the sentence.

Late last month prosecution referred Seif to urgent trial over accusations of insulting a member of the public prosecution while she was being investigated in another case related to calling for protests against the recently signed border demarcation agreement between Egypt and Saudi Arabia.

She was then released on bail pending the court's ruling.

Last September, Seif  was released among 100 other prisoners after a presidential decree pardoned them.

Seif is the sister of prominent political activist Alaa Abdel Fattah, and was part of a group arrested on June 21, 2014 while taking part in a march calling for the repeal of the protest law and the release of all those arrested for violating it.

The protest law, which was issued in 2013, imposes a practical ban on street demonstrations by requiring organisers of protests to obtain prior permission from the interior ministry.
