Robert Lewandowksi, Arturo Vidal and Thiago Alcantara were all forcibly removed from the official's dressing room by police after their controversial exit from the Champions League at the Bernabeu.
Reports in El Chiringuito claim that the three Bayern Munich stars were so incensed by some of the questionable refereeing decisions that they stormed in to the Hungarian official's dressing room and began hurling insults and abuse at both the ref and linesmen.
The Pole, Chilean and Spaniard refused to leave the room until police came in and dragged them away from their verbal tirade against referee Victor Kassai.
Their furious reactions came after they were dumped out 4-2 on the night and 6-3 on aggregate by Real Madrid, who advance to the semi-finals of the Champions League for the seventh consecutive time.
Needing to win by two clear goals following a 2-1 defeat at home in the first leg, Bayern went ahead on the night thanks to a Robert Lewandowsi penalty. Cristiano Ronaldo scored an equaliser, but Sergio Ramos stuck through his own net two minutes later to level the tie at 3-3 on aggregate.
But, the match swung six minutes from time when Arturo Vidal was given a second yellow card for a seemingly legitimate tackle. In extra time, the ten men from Bavaria could not with stand the pressure Real put on them, as Ronaldo completed his hat-trick and Asensio added a fourth. However, extra time proved controversial also as both of Ronaldo's goals were clearly offside, yet allowed to stand.
The trouble after the match was also part of wider trouble at the game, after riot police were deployed to the stands to quell trouble in the upper tier of the travelling supporter's section. Fans kicked off when there was a dispute with stewards as to what banners they were allowed to hang and where.
Despite some horrendous officiating - which is sadly not unexpected at the top level of the game anymore - the players behaviour is inexcusable. Retribution against both the three men and the club will likely be swift and forthcoming from UEFA.
