Recently a security officer who at the time working for a local authority on a subcontracted basis, intervened in an incident and possibly saved a man's life by restraining him and using handcuffs to control him. 

The police were called and took the man away and didn't have any issue with the fact he'd used handcuffs.

A short while later a safeguarding officer for the local authority he was working for investigated the incident and said that they were reporting him to the SIA for professional misconduct as because he handcuffed the male, after the SIA allegedly told the council handcuffs were a breach of his licence.

Then a police officer said that he wanted to see his license to carry handcuffs.
