Question to the Home Office:

To ask His Majesty's Government whether they keep records of perpetrators of knife crime by (1) gender, (2) ethnicity, and (3) age.

Police forces maintain details of perpetrators of knife crime on local record management systems and this will usually include key demographic data. However, when a suspect has not been arrested this may be based on the perception of the victim or witness rather than their actual characteristics.

The Home Office only collects detailed records from forces on the sex, age and ethnicity of suspects of homicides committed by a knife or sharp instrument.
