The Egyptian news service Bikya Masr said the beatings occurred late Tuesday outside Cairo stadium following an Egypt Cup game between the al-Ahly and Kima Aswan teams. Police said they were provoked by al-Ahly soccer club fans chanting slogans against the ministry of interior and ousted Egyptian President Hosni Mubarak.
Video posted online showed police chasing fans from the stadium, the report said.
The al-Ahly club Web site said one person was killed, Bikya Masr said. Police did not confirm the report.
Officials said more than a dozen police vehicles were vandalized during the fighting.
Mubarak, his former minister of interior and six top aides are currently facing trial for ordering the killing of 850 protesters earlier this year.
