With the support of the Home Office Scientific Research & Development Branch and the Metropolitan Police, I developed a prototype to computerise the Metropolitan Custody Record in Turbo Pascal.

The Custody Record is a multi-page form that officers fill in when someone is charged and is in custody at a police station. It is used to log their details and events, such a lawyer visits.

I spent a day at a charging table at Holloway police station to see how people are originally processed.

I worked with a police officer to refine the design.

The finished prototype was presented at a police conference.
