If you recieve a threat
If you or a family member receives a threat, this should always be treated as legitimate and serious until proven otherwise.
The first thing to do is:
Consider if it should be escalated to the Police
If a threat is serious, personal and involves a physical threat to you or your family, then you should consider taking the threat to the Police in the first instance.
