April 6 founding member and former head Ahmed Maher finished on Monday a three-year sentence on charges of breaking the Egyptian protest law.
Maher's lawyer Khaled Ali told Ahram Online that procedures for his release will begin on Tuesday and are expected to take a week.
Maher, along with April 6 Youth Movement co-founders Mohamed Adel and Ahmed Douma, was charged in late November 2013 with illegally protesting and assaulting police officers outside a Cairo court while he was handing himself in for questioning over accusations of illegal protesting on 26 November.
In December 2013, an Egyptian misdemeanour court sentenced all three activists – who were at the forefront of Egypt's 2011 uprising that toppled autocrat Hosni Mubarak – to three years in jail and fines of EGP 50,000 each on charges that included organising protests without seeking a police permit.
Adel will also finish his sentence within the month, according to Ali.
Douma, however, is serving a life sentence in another case and is awaiting an appeal trial in April.
