The office of the Bulgarian Football Union has suffered heavy damages after an attack by angered CSKA Sofia fans Saturday.

The windows and door of the office have been broken and part of the inscription has been removed.

There are damages even to the above ground floors, according to the Bulgarian Focus Information Agency.

Police have closed down the area, located on the central Ivan Asen II Str. in Bulgarian capital Sofia.

CSKA fans are currently protesting in front of the team's stadium in the nearby Borisova Gradina park.

The rally has been provoked by the takeover of the team by former football legend Hristo Stoichkov, and its possible merger with the team of Litex Lovech.

The change of ownership comes after years of financial trouble and unconvincing performance by CSKA, which however finished third in Bulgaria's latest national football championship.
