Referee John Beaton has been forced to contact Police Scotland after receiving abusive messages online, according to reports.
The man in black took charge of the Old Firm derby between Rangers and Celtic on December 29 and had his work mobile number leaked online.
Beaton’s performance drew criticism from Parkhead fans and officials after he failed to take any action against Alfredo Morelos despite three altercations with Celtic players.
But in a sickening turn of events it is understood Beaton has been forced to contact Police Scotland after his mobile number was leaked on social media.
Trolls have since bombarded the official with dozens of threatening and abusive messages and Beaton is now waiting to speak to officers.
The 36-year-old admitted he saw three incidents with Morelos, but chose not to punish the Colombian.
Celtic released a statement demanding answers from the official and will look to meet with Maxwell and the SFA’s head of refereeing, John Fleming.
The statement read: “Celtic Football Club is surprised that there will be no disciplinary action taken by the Scottish FA regarding the incidents during the match on December 29, which have been widely addressed in the media.
“It is reported that no action was taken because the match referee saw all of the incidents in question.
“Given that the referee took no action at the time, this tends to suggest that such conduct, which in one instance led to a Celtic player, Anthony Ralston, being injured, is acceptable in Scottish football. That cannot be right.
“On the day, Celtic did not play well enough to win the match, something we accept. However, this issue goes beyond the result of the match.

“Celtic is not the only club this season to raise concerns regarding the standard of officiating at matches in Scotland, concerns which have also been shared by many commentators on the game.
“In order to fully understand what is going on, Celtic, our supporters, Scottish clubs and the general Scottish football public need transparency in these matters, and we therefore call on the Scottish FA to allow the referee, John Beaton, to explain these decisions publicly as well as any match officials involved in other similar circumstances.
“In the meantime, we have requested a meeting with Scottish FA chief executive, Ian Maxwell, and the Association’s Head of Refereeing.”
