Egypt's ousted president Hosni Mubarak was taken back to prison from an army hospital on Thursday after appearing fitter at his aborted retrial on charges of complicity in the killings of protesters in 2011.
Hundreds of his supporters blocked the road in front of the hospital late on Wednesday, delaying the transfer, the MENA state news agency said.
"We love you Mubarak" and "Down, down with the rule of the Muslim Brotherhood," chanted the protesters, referring to new President Mohamed Mursi's group.
The retrial of Mubarak will start again on May 11, a Cairo appeals court said on Wednesday. A first attempt collapsed on Saturday when the presiding judge withdrew from the case and referred it to another court.
Judge Mustafa Hassan Abdullah had been widely criticised for acquitting security men accused of attacking protesters in an incident in which crowds were charged at by men riding camels during the 2011 uprising which overthrew Mubarak.
