## Is CO2 safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in CO2 at a rate of 100.9 per 1,000 people.
That compares with 83.5 per 1,000 people across the CO postcode area.
In August 2026 alone, 352 cases of crime and anti-social behaviour were recorded in CO2.
In the 12 months to August 2026, the most common types were violence and sexual offences (1,918), other crime (757) and anti-social behaviour (528).
A year earlier, the recorded crime rate in CO2 was 92.5 per 1,000 people.
Worked out by Open Index from police.uk crime records and ONS and NISRA population estimates.
Rates are per resident, so places that many people work in or visit, such as Westminster, the City of London and other city centres, have far higher rates than their residents alone would suggest.
