"I definitely believe these repeated arson attacks are planned. They always occur in the archive sections where evidence in important trials is being held. And not only those concerning the revolution, but also major tax-fraud trials," Judge Ashraf Nada said Thursday.
Nada said documents in corruption trials for two officials from the administration of ousted Egyptian leader Hosni Mubarak were kept in the South Cairo Criminal Court archive, which was damaged by fire Thursday.
Ahram Online said the fire, which started in the prosecution offices, took 5 hours to put out.
A number of other governmental buildings have been damaged by fire since civil unrest erupted in January,, Ahram Online said.
The string of fires at government and court buildings includes a March 11 blaze at the Administrative Control Authority, which is responsible for combating government corruption.
