Mubarak has been released from prison, according to state television. The 85-year-old longtime autocrat was taken from Cairo's Tora prison by medical helicopter, following a court ruling which ordered his release.
Mubarak will still remain under house arrest pending trial.
He was initially taken to a military hospital in Maadi, a suburb in southern Cairo.
A small crowd of supporters gathered outside the prison and cheered as the helicopter took off.
Meanwhile, the April 6 youth movement has called protests on Friday against his release.
