## Is CO7 safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in CO7 at a rate of 48.9 per 1,000 people.
That compares with 83.5 per 1,000 people across the CO postcode area.
In August 2026 alone, 169 cases of crime and anti-social behaviour were recorded in CO7.
In the 12 months to August 2026, the most common types were violence and sexual offences (784), other crime (320) and anti-social behaviour (161).
A year earlier, the recorded crime rate in CO7 was 44.6 per 1,000 people.
