Cairo - Discontent in Egypt's police ranks has boiled over into an unprecedented strike, with officers saying they will refuse orders until they are no longer used as political pawns, adding to the problems of President Mohamed Morsi.
Accused of excessive use of force by the opponents of Morsi and his Muslim Brotherhood, police officers say they feel despised by the people when they are simply following orders - and they will not take any more.
"We are suspending our work indefinitely because we refuse to take responsibility for the mistakes of a government that wants to get involved in political conflicts," said police Colonel Hassan Mostafa.
"All of society is against us...it considers the demonstrators (killed in clashes) to be martyrs, and we don't even have the right to defend ourselves," he added.
The police, particularly the Central Security Forces (CSF), have been engaged in violent and deadly street clashes with protesters, turning the public even more against an already reviled institution long accused of abuses.
The CSF is the branch of the interior ministry used to quell protests.
The police want a law to clearly lay down their powers and duties and have also demanded weapons to deal with ongoing political protests.
The police "are paying the price of a political conflict.
They risk prosecution (over the deaths of protesters) or getting killed" in clashes which have spiked since the end of 2012, General Abdel Tawab Hefni of the police headquarters in Alexandria told the independent daily Al-Shorouk.
The discontent began weeks ago with isolated pockets of protest, but by Thursday police were on strike in areas of Cairo, Alexandria, the Nile Delta, the Suez Canal provinces, southern provinces and the Sinai Peninsula.
In an attempt to ease tensions, Interior Minister Mohamed Ibrahim on Friday sacked the head of the CSF and appointed a new chief.
But his announcement did little to placate angry police, who said they will pursue their protest.
"We will continue our strike until the government accepts our demands, which are to keep the police of politics, stop the 'Brotherhoodisation' of the police (the appointment of Muslim Brotherhood members to key posts) and the dismissal of the interior minister," Colonel Mohamed Fawzi of Cairo police told Al-Shorouk.
Ibrahim on Sunday pleaded for an end to "rumours" of police abuse, saying his forces had not fired a single shot at protesters since the start of the 2011 uprising.
He sought to dispel accusations that he was close to the Brotherhood, and tried to paint a united front among police, saying that those on strike were a minority, adding that he also wanted to be kept out of politics.
"We call on everyone to keep us out of their equations. We don't belong to any faction, ideology, opposition," Ibrahim said.
Protests have also been staged among CSF members.
In the port city of Ismailiya, CSF officers refused to be deployed to neighbouring Port Said, where clashes since the end of January between police and protesters have killed more than 48 people, including three policemen.
Morsi called in the army to secure the city on Friday.
Police in Egypt have been reviled for decades by much of the population. And despite the ouster in early 2011 of Hosni Mubarak's autocratic regime who relied on massive force to quell dissent, it is still considered a repressive institution.
According to local rights groups, more than 70 protesters have been killed since November 2012.
Two protesters were killed in renewed clashes in Cairo on Saturday.
