The PGMOL released a statement on Sunday evening which read: “We are appalled by the threats and abuse directed at Michael Oliver following the Wolverhampton Wanderers v Arsenal fixture.
“No official should be subject to any form of abuse, let alone the abhorrent attacks aimed at Michael and his family over the past 24 hours.
“The police are aware, and a number of investigations have commenced. We are supporting Michael, and all those affected, and are determined to tackle this unacceptable behaviour.
“Sadly, this is not the first time a match official has been forced to deal with threats in recent times. We will continue to support all investigations.”
