Abusive calls

Malicious, abusive or threatening calls, whether from people you know or from strangers, are a criminal offence.

Immediately call your phone company and ask for their nuisance or malicious calls team.

If the caller is making direct threats to you or your family and you believe those threats to be real and immediate, you must call 999 straightaway.

If you believe that the threats made are not immediate, then you should call your local police station (101 from any landline or mobile phone).
