Tref Cybi, Isle of Anglesey: Safety
Safety
Crime levels in Tref Cybi are higher than the Welsh and UK averages, but there's been real progress. Recorded crimes dropped from 284 to 184 per 1,000 people between 2024 and 2025 — that's a 35% fall year on year.
This improvement is significant. Anti-social behaviour, drug offences, burglary, and criminal damage all fell noticeably in 2025.
Violent crime is still the biggest crime category here, as it is across most UK neighbourhoods. Vehicle crime, though, is low compared to national figures.
The neighbouring neighbourhood of Ynys Gybi shows the same pattern of improvement, which suggests the positive change is happening across the wider area rather than just in one spot.
