Dozens of protesters have remained in Cairo's Tahrir Square after camping out following the mass demonstration against verdicts handed down in Mubarak's trial.

Fresh protests were expected in both Cairo and Alexandria later on Wednesday, to mark the second anniversary of the killing of Khaled Said, a young Egyptian beaten to death in police custody in 2010.

Said became the symbol of police repression and of the uprising that overthrew Mubarak.

A silent march was expected to take place in Cairo, while a symbolic "funeral march" was planned to kick off from Said's home in Alexandria.

Said, 28, was detained in an Alexandria internet cafe and then beaten to death. His killing angered youth activists, some of who set up the "We are all Khaled Said" Facebook page in his memory.

The page now has two million members, and was one of the first to call for protests against Mubarak's regime on January 25 last year. [AFP]
