Question to the Home Office:

To ask the Secretary of State for the Home Department, how many people were arrested for carrying a dangerous weapon in 2018.

The Home Office collects and publishes data on the number of arrests at the offence group level, including ‘possession of offensive weapons’ offences.

Data on the number of arrests for ‘possession of offensive weapons’ are published annually, on a financial year basis, in the ‘Police Powers and Procedures, England and Wales’ statistical bulletin. The latest data, covering the period up to March 2018, can be accessed here:
