Police Officer Firearm Discharges

I was looking to get the number of incidents where a PSNI officer discharged their weapon between January 1, 2015, and November 18, 2020 (day of FOI application) - either accidentally or purposefully.

I am looking the numbers to be broken down by year, in which policing district the discharge happened, how many rounds were fired in each incident, what weapon was used, why it was used and, if applicable, detail any injuries that were sustained.
