Trouble flared at Sunday’s Bulgarian third division match between Minyor Pernik and CSKA Sofia as fans from both teams tried to get at each other.
In the middle of the second-half, several CSKA fans ran onto the pitch and started goading their Minyor opponents. A number of furious Minyor fans came onto the pitch and tried to get at them but were prevented from doing so by cops.
Trouble then broke out in the CSKA section of the ground between fans and riot police.
There were no reports of arrests.
