Ten policemen in Egypt have been charged with torturing a man to death at a police station in Cairo in November, a judicial source and the victim's lawyer said on Sunday. Rights groups say police brutality is widespread in Egypt, enabled by a culture of impunity, and a string of incidents have triggered protests and riots in the past year. Anger at police was also major factor in setting off the 2011 uprising that ended President Hosni Mubarak's 30-year rule.
