On the surface, the Home Office’s latest data on terrorism arrests looks relatively stable. There were 255 terrorism-related arrests in 2025, which is only a 2% increase on the previous year’s figure of 250.
Funny thing is, I know three people who were arrested on terrorism-related charges last year. I could even pinpoint the date, because two of their middle-aged children had to leave my middle-aged birthday party to pick them up from a police station. I know, I know, it’s not all about me, even if it was my birthday – but if those numbers are solid, that means more than 50% of the mini-surge came from more or less the same group of people, two of them from the same postcode.
