Increased security and drone surveillance for CSKA Sofia vs. Levski derby on 27 April

The Interior Ministry is planning an extra police presence in the capital for the final derby of the season between professional football clubs "CSKA - Sofia" and "Levski", which will take place on 27 April at the "Vasil Levski" national stadium in the capital.

In addition to increased police presence, drones will be used during the match to identify offenders, who will be arrested either on the spot or immediately after the match.

Traffic is expected to be disrupted as fans march through the streets.

The previous meeting between the two teams on 7 April was marred by disturbances in the stands, rockets being fired from the stands and fans attempting to break onto the pitch.
