04/06/2011 - Cairo - Egyptian officials say they're investigating the death of a bus driver who was beaten following a fight with a police officer.
After the death, angry protesters attacked a police station.
Hundreds of angry protesters pelted a Cairo police station overnight and torched an armoured vehicle. Police fired tear gas to disperse the crowd.
Details of how Mohammed Nasr died were unclear.
Mohammed Abdel-Aziz, a lawyer specialising in torture cases, said on Saturday that he received contradictory statements about Nasr's death.
The incident has riled many Egyptians.
Widespread police abuse was one of the driving forces behind the mass protests that erupted in January and forced President Hosni Mubarak to step down.
