Trending: Egyptians share revolution stories ahead of fifth anniversary

Hundreds of Egyptians have taken to social media to share their stories and opinions of the 25 January revolution only a few days ahead of its fifth anniversary.

The Arabic-language hashtag "I took part in the January revolution", which is currently trending on Twitter, was launched in response to the arrest of Taher Mokhtar, a member of the Freedoms Committee at the Doctors Syndicate and a long-time revolutionary socialist activist.

On Thursday, security forces stormed Mokhtar's apartment in downtown Cairo, arresting him along with his friends Ahmad Hassan and Hossam al-Din Hamady.

The three were then taken to Abdeen police station for interrogation.

Mokhtar, who had been actively campaigning against medical negligence in Egyptian prisons, was accused of taking part in the January revolution.

On Sunday, dozens of people, including human rights activists and political figures, signed an online petition in solidarity with Mokhtar, denouncing the charges against him.

More than 3,300 people have joined the petition's Facebook page in less than one day.

"The regime has begun to turn participation in the revolution into an official charge," the petition read.

"We are all 'guilty' of taking part in the revolution, and we will never deny it," the petitioners added.

"We will continue to fight until all detainees are released, and until we achieve the justice and freedom demanded by the Egyptian people who took to the streets five years ago."

Human rights activists, media professionals, political figures, poets, intellectuals, and others who took part in the protests contributed to the trending hashtag to stress their pride in the revolution and willingness to continue the fight against corruption and oppression.

Translation: This revolution encouraged me to leave everything and return to Egypt, after I had vowed never to return because of all the corruption I had seen at work.
