A court in Alexandria, Egypt, has sent leading Revolutionary Socialist and human rights lawyer Mahienour el-Massry back to prison following an appeal hearing on Monday.
She was appealing a two year sentence served on her after a protest outside an Alexandria police station in March 2013.
The appeal ruling has now been postponed.
Mahienour and another defendant, fellow Revolutionary Socialist Youseff Shaaban, have now both been remanded in custody until 31 May.
The case centres on a protest by lawyers and supporters. They went to the Raml police station demanding an apology after cops assaulted another lawyer.
Police arrested Mahienour and Youssef and eight others and accused them of trying to storm the police station.
She has already served four months of a six month sentence in a separate case last year. She was accused of breaking the military regime’s draconian anti-protest law.
Mahienour had been demonstrating in Alexandria during the retrial of police officers who killed political blogger Khaled Said under Hosni Mubarak’s dictatorship in 2010.
Mahienour won the prestigious annual Ludovic Trarieux award last year for her work defending human rights.
