At least 100 demonstrators have rallied near Egypt's security police headquarters to demand the resignation of the country's interior minister and the prosecution of security officers whom they accuse of torture.
Participants in Sunday's demonstration in Cairo included Egyptian human rights activists.
International and Egyptian human rights groups have criticized Egyptian prisons, police stations and detention centers for what they say is widespread brutality and torture.
The U.S. State Department's latest human rights report said Egypt has a poor human rights record.
Egypt agreed two years ago to create a national council on human rights to investigate allegations of rights abuses. But the government has frequently denied abuse allegations.
