The deputy head of Egypt's Doctors Syndicate Mona Mina has been released on EGP 1,000 bail after four hours of questioning by Cairo prosecutors.
Mina was summoned to appear before the prosecution after cases were filed against her by Egypt's health minister, the head of Cairo University, and lawyer Tarek Mahmoud.
Mahmoud accused Mina of "disturbing security and social order, spreading panic among citizens, and defaming the state."
Mina came under fire recently after stating publically that hospitals in the country have substandard hygiene practices.
Mina is an outspoken proponent of better wages and working conditions for doctors and an advocate for healthcare reform.
A statement of solidarity with Mina has been signed by over 500 prominent figures and activists as well as a number of professional syndicates following the backlash over her comments.
In 2012, Mina, a long-time leftist activist, became the first woman to become secretary-general of the Doctors Syndicate.
Mina, a founding member of the Egyptian activist group Doctors Without Rights, has also been politically active beyond the scope of her profession, participating in anti-regime protests since the era of former president Hosni Mubarak.
