Hundreds of Egyptian soccer fans rallied in the capital Saturday to demand the release of fans who were detained in a protest this week.

Fans of Cairo's Al-Ahly club, known as ultras, marched to the main judiciary compound in Cairo. They want the chief prosecutor to drop an investigation of 25 fans who were taken into custody on Tuesday during a demonstration at Cairo International Airport. Authorities contend some protesters attacked security personnel at the facility.

Nineteen of those detained have since been released on bail while six others remain in custody.

On its Facebook page, Ultras Al-Ahly said Saturday's demonstration was to demand the release of the fans. At the rally, fans wearing Al-Ahly's signature red T-shirts were chanting: "Ultras are not criminals."
