Decision

I have today decided to disclose the located information to you in full. Please find below information pursuant to your request above.

Knife crime accuracy figures are not always on target and this needs to be taken into account with some of the finer numbers.

Also, as age is not a mandatory field within the CONNECT system there are likely data inaccuracies within some of these results to be considered.
