According to media reports, the feud began after a fallout between Ross McGill, the former head of Rangers Football Club’s ultras fan group the Union Bears, and convicted Edinburgh drug dealer Mark Richardson – who is currently in prison.

The force said it responded to 84 incidents of violence and disorder, arrested 64 people and executed 55 search and arrest warrants.

Seven firearms and “assorted weapons” were recovered, and over 90 safeguarding plans were put in place to protect vulnerable people caught up in the feud.

Of the Operation Portaledge cases which have come to court, several have resulted in lengthy jail sentences.

Arran Reid was imprisoned for eight years and four months after admitting carrying out a machete attack on an Edinburgh businessman linked to Richardson.
