A prominent Egyptian dissident has been arrested, six months after his release from prison, his family says.
Alaa Abdel Fattah was freed in March after serving a five-year sentence for organising a protest without permission.
He was a leading campaigner during the 2011 uprising against former Egyptian President Hosni Mubarak.
Under his probation conditions, the activist was required to spend nights in a police cell for five years.
On Sunday, as Mr Abdel Fattah was preparing to leave the police station, he was rearrested by Egyptian authorities, his family says.
“I arrived at the police station and I found the place where he spends the probation empty,” his sister Mona said.
Reports say Mr Abdel Fattah was arrested over allegations of publishing false news and inciting people to protest.
Human rights groups say about 2,000 people have been arrested since scattered anti-government protests erupted in Cairo and other cities last week.
