Question to the Home Office:

To ask the Secretary of State for the Home Department, how many times stop and search was used by Lancashire Constabulary in 2018; and (a) how many convictions there were for crimes involving the use of knives and (b) how many of those convictions resulted from arrests following stop and search in Lancashire in 2018.

The Home Office collects and publishes statistics on the number of stop and searches conducted by each police force in England and Wales and the number of resultant arrests. These data are published in the ‘Police Powers and Procedures, England and Wales’ statistical bulletin, which can be accessed here:

In 2017/18, Lancashire Police conducted 3,284 stop and searches in total.

The Home Office does not collect data on outcomes of prosecutions. Nor does the data collected by the Home Office on stop and searches allow for the stop and search to be tracked through the criminal justice system to the outcome of a prosecution.
