Hundreds of Egyptian police officers, central security forces, detectives and rescue workers began an open-ended strike on Thursday by Tanta's security office.
Major Ahmed al-Hateemy said that their demands include the sacking of the interior minister, amendment of Article 199 of the constitution and independence from the presidency.
They announced their rejection of, what they described as, the "Brotherhoodization" of the police apparatus.
Meanwhile, central security recruits had started strikes in different locations in Tanta, demanding that they be equipped to face acts of violence and thuggery and for their victims to be treated like the uprising's "martyrs".
The protesters threatened of escalations including refraining from protecting public installations and police offices while several security groups have announced their solidarity.
They forced a Al-Jazeera television team out of the strike, accusing the Qatari-owned channel of defaming the image of the interior ministry.
