CAIRO—Hours after marching in a peaceful protest against the government late last month, Yassin Mohammed and his friends were lingering in the area in a district of the Egyptian capital when police descended on them, piled them into a minibus and took them to a police station. There, he said, he was blindfolded, handcuffed and beaten by security agents.
Now the 21-year-old Mohammed, released on bail, faces trial on charges of breaking a 2013 law that virtually bans any street demonstrations. He knows how heavy the penalty can be. Two years ago, he was sentenced to a total of 17 years in prison for joining protests—and he said he nearly committed suicide in his cell out of despair until a fellow inmate stopped him.
Mohammed is among those caught up in one of the biggest waves of arrests in the past two years in Egypt, a sweep that signals a fierce zero-tolerance stance by the government of President Abdel-Fattah el-Sissi over any sign of unrest.
