Where a constable arrested someone based upon information on the police national computer, he was not to be held accountable for wrongful arrest and false imprisonment, if the information upon which that had in turn been based, did not justify the suspicion. The issue was whether the constable acted reasonably in relying upon that information. The entry itself was reasonable and objective cause for his suspicion, and arrest of the claimant. If information received from a member of the public could be an appropriate basis for an arrest, why should that same information cease to be such a basis when transformed into an entry on the computer.
The chief constable appealed against a finding of false imprisonment and assault, saying the claimant had been arrested properly. He was a passenger in a car which was mistakenly listed as ‘of interest’.
Held: The chief constable’s appeal succeeded. The critical question to be asked in all cases is what is in the mind of the arresting officer: he can never be a ‘mere conduit’ for someone else. It is for that reason insufficient for an arresting officer to rely solely upon an instruction to carry out the arrest. Conversely, however, where the arresting officer’s suspicion is formed on the basis of a police national computer entry, that entry is likely to provide the necessary objective justification. If information from an informer or member of the public can properly found suspicion sufficient for an arrest, why too should not an apparently responsible entry in the computer?
