Police Scotland has confirmed an investigation is underway over 'alleged threatening communications' towards referee Kevin Clancy after an SFA probe.
The governing body's chief Ian Maxwell condemned 'potentially criminal' abuse the experienced referee faced following Saturday's dramatic Old Firm derby. Clancy was the match official as Celtic won 3-2 but with rivals Rangers writing to the SFA to seek clarification over a key decision involving a disallowed goal for striker Alfredo Morelos.
The Ibrox outfit then revealed their 'astonishment' at the verdict from the SFA that the decision was 'correct'. Rangers also condemned 'in the strongest terms any abuse of match officials'.
