Police – Assault on constable in execution of duty. Although the grabbing of the appellant by a police officer had been an unlawful use of force, the Crown Court had been entitled to find, on the facts found, that another officer had been acting in the execution of his duty when he had been bitten by the appellant, as the appellant had used unreasonable force to defend his liberty. Accordingly, the Divisional Court dismissed the appellant's appeal by way of case stated against his conviction for assaulting a police officer in the execution of his duty.
