“Violent” is police.uk’s violence and sexual offences (which includes harassment, stalking and assault without injury), robbery and possession of weapons. Anti-social behaviour isn’t a crime category; shoplifting and other theft happen mostly in shops and town centres rather than to residents, so neither counts in the grade.

And about 12 burglaries, vehicle crimes or acts of criminal damage, plus 4 shoplifting and theft reports, in the 12 months to August 2026. Each dot is one resident; each coloured dot is one recorded crime.
Police name a suspect about as often as across UK towns
No suspect was identified for 73% of Trelewis’s burglaries, vehicle crimes and criminal damage, against 69% across UK towns, and for 22% of violent and sexual offences against 19%. Most violent cases close as “unable to prosecute” (65% here), usually because the victim doesn’t support a prosecution. About 5% of violent and 0% of household crimes reached court.
The latest outcome police.uk shows for each crime recorded in the first of the three years (September 2023 to August 2024), so most cases have closed. 106 crimes.
No one died in a collision on Trelewis’s roads in 2021–2025
Police recorded 9 collisions with injuries inside Trelewis in five years. 2 people were killed or seriously injured: 1 on foot and 0 on a bicycle.
Most UK towns of 1,000 to 2,500 people (94%) had no road deaths in these five years, and Trelewis is one of them.
Counting serious injuries too, a town of Trelewis’s size at the median for UK towns of 1,000 to 2,500 people would see about 1 people killed or seriously injured in five years; Trelewis had 2.
Casualties are counted where the collision happened, not where people lived: a main road through town adds through-traffic, and residents’ own risk on roads elsewhere isn’t here. Seriously injured uses the Department for Transport’s adjusted figures, which even out the police forces’ different ways of recording injuries. There’s no national rate here: more than half of road deaths in England and Wales (58%) happen outside every town’s built-up area. Source: DfT road casualty statistics (STATS19), 2021–2025.

What this data can and can’t tell you
- Where crimes happen, not where victims live. police.uk places each crime at a point near where it happened. Town centres with shops, stations, a hospital and nightlife record more crime per resident, and residents of nearby villages who come in to shop or go out are part of that count.
- Bigger towns record more per resident. Across UK towns, recorded crime per resident rises steeply with size, more than in the U.S., so a city’s grade sits low against the whole UK. The “towns its size” figures show where Trelewis sits among towns like it; they are context and don’t change the grade.
- Points are approximate. police.uk moves each point to the nearest of a set of anonymous map points, so crimes near the edge of the built-up area can fall either side of it.
