Arrest – Unlawful arrest. The claimants issued proceedings against the defendant Metropolitan Police Commissioner for unlawful arrest and assault. The judge dismissed the claims on the grounds that the police had acted on a reasonable belief that the claimants were implicated in a recent burglary, influenced by a collision between the claimants' and police vehicles. The claimants appealed. The Court of Appeal, Civil Division, in dismissing the appeal, held that it had been the Commissioner's case that the vehicles had come into contact in a manner which had reasonably fuelled the officers' suspicion that the claimants had been implicated in a recent crime. Further, his findings had been open on the evidence.
