Another eight people were detained by Bulgarian police after the match at the Vasil Levski stadium that was temporarily halted by the Croatian referee under a three-step protocol devised by European soccer governing body UEFA.
UEFA has said it is opening disciplinary proceedings against Bulgaria on a number of charges including racist behaviour and the throwing of objects.
