Billy Dewar-Riddick, who taught music in primary and secondary schools, outraged fellow staff members.

A teacher who abused colleagues on a night out and claimed his wedding ring was a ‘slut magnet’ has escaped a ban from the classroom.

Billy Dewar-Riddick labelled one teacher a ‘slag’ and asked questions about others sex lives during a drinking session in a pub.

Dewar-Riddick, who taught music in primary and secondary schools, outraged fellow staff members during a night out in the Anglers Bar in Annan.

During the boozy night out in 2018, shamed Dewar-Riddick was escorted from the premises but then returned and slammed a bottle down in front of a colleague and told her: “There’s a bottle for you, you slag.”

He also made unwanted physical contact with another colleague and grabbed her on the lower back. Dewar-Riddick, of Dumfries, was hauled before an education watchdog who found a string of allegations against him proved but stopped short of ordering he be struck off.

The General Teaching Council for Scotland (GTCS) heard he had spoken inappropriately about his wedding ring and also quizzed male and female staff about their sex lives.

He claimed some of the incidents were ‘banter’ and that he was fit to be a teacher. Dewar-Riddick told the probe he had received an absolute discharge over events in the pub after he admitted a breach of the peace charge.

He admitted adding himself to one colleague’s Snapchat profile without permission and labelling one colleague’s friend a ‘c**t’. He also confessed to shouting ‘who the f**k are you’ and ‘slag’ ‘whore’ ‘slut’ ‘tramp’ ‘woman’ and ‘c**t’ towards a colleague.

The GTCS spared him a ban after hearing he had sought ‘remediation’ and that it was not in the public interest to remove him from the classroom. He said he had been under ‘significant stress’ at the time and that his conduct had been ‘isolated’.

In a written ruling, the GTCS said: “The panel decided the behaviour found has been remedied, there is good evidence of positive behaviour by the teacher within and out with school.

“There is no public interest requirement in a finding of impairment. The panel found that the teacher’s fitness to teach is not impaired.

“Accordingly, for the reasons set out above, the panel determined that the teacher’s conduct, as at today’s date, does not fall short of the standards expected of a registered teacher and that his fitness to teach is, therefore, not impaired.”
