A man who persistently and needlessly caused a drain on emergency services has been jailed.
Robert Humphreys Trevelyan (39), of Haulfryn, Ruthin was already serving a suspended prison sentence for unrelated offences, when he was involved in several incidents requiring police a presence, as a result of being intoxicated or under the influence of drugs, with his behaviour having a significant impact on the wider community.
Following his arrest for offences involving members of the public, Trevelyan began a series of calls to emergency services, often being verbally abusive to police and ambulance service call handlers, and he subsequently refused to engage with partner support agencies.
Trevelyan was arrested, and despite being released with bail conditions not to contact emergency services unless in a genuine emergency, he continued to ring North Wales Police and the Welsh Ambulance Service whilst intoxicated.
Trevelyan made a total of 35 emergency 999 calls between the 24th May and his further arrest on the 17th June 2026.
In total, since January 2026, he made 74 nuisance emergency 999 calls.
Trevelyan was subsequently charged with the following offences:
- Two counts of Assaulting an Emergency Worker
- Possession of a class B drug
- Criminal Damage.
- Common Assault.
- a hate related offence under the Communications Act 2003
- Two counts of Persistently making use of a public communication network to cause annoyance / inconvenience / anxiety,
- Causing to be sent by a public communication network an offensive / indecent / obscene / menacing message / matter
- two counts of an offence under Section 5 of the Public Order Act
- and Wilful obstruction of a highway.
The Court heard how Trevelyan’s course of conduct placed a significant demand on both emergency services, with Welsh Ambulance Service University NHS Trust estimating how his behaviour in the month of December 2025 alone had cost their service close to £10,000, with more than 16 ambulances being sent out to him.
At Court last week, his previously suspended sentence was activated, and he was sentenced to 84 weeks in prison, with a 3 year Criminal Behaviour Order put in place.
As part of his Criminal Behaviour Order on his release, Trevelyan is prohibited from
Contacting North Wales Police or Welsh Ambulance Service unless in a genuine emergency.
Speaking after sentencing, PC Ffion Montgomery said: “This sentence sends a clear message that anyone misusing the 999 service will be dealt with robustly.
“Abuse of the 999 lines delays us speaking to those reporting genuine emergencies, and abuse of call handlers who are there to help will not be tolerated.”
