What details should I give PSNI after catalytic-converter theft in Northern Ireland?

Give PSNI the vehicle registration, make/model, exact location, the time window in which the theft occurred, any CCTV or witness details and descriptions of suspicious people or vehicles. Keep receipts or identifying information for replacement and insurance purposes.

For this Northern Ireland query, the practical issue is what details should I give PSNI after catalytic-converter theft in Northern Ireland. Vehicle crime should be dealt with quickly because the first few hours can matter for recovery, CCTV retention, tracker data and forensic evidence. PSNI advises owners to contact police as soon as they become aware that a vehicle has been stolen, damaged or broken into and to touch as little as possible where forensic evidence may remain.

Keep the vehicle registration, VIN, insurer details, photographs and security-device information somewhere you can access even if the car or documents are stolen. Save original CCTV or dash-cam files before they overwrite. When reporting an incident, separate what you know from what you suspect and give PSNI accurate times, locations, vehicle details and reference numbers. For this question specifically — “What details should I give PSNI after catalytic-converter theft in Northern Ireland?” — the safest answer is the one above, based on the current Northern Ireland and UK official guidance rather than forum advice or rules written for another jurisdiction.
