you"). But inequality in size can be disregarded so if a very small person threatens a very large person and it is obvious that the risk of any real injury from this attack is remote, the large person may nevertheless feel some degree of apprehension. Normally, both the one making the threat and the victim must be physically present because, otherwise, there would be no immediate danger. However, if a mobile phone is used to transmit the threat (whether orally or by SMS) and, from the words used, the victim reasonably understands that an attack is imminent, this may constitute an assault. In Fagan v Metropolitan Police Commissioner a police officer ordered the defendant to park his car and he reluctantly complied. In doing so, he accidentally drove the car on to the policeman's foot and, when asked to remove the car, said "Fuck you, you can wait" and turned off the ignition. Because of the steel toe cap in his boot, the policeman's foot was not in actual danger, but the Divisional Court held that this could constitute an assault. Albeit accidentally, the driver had caused his car to rest on the officer's foot. This actus reus was a continuing act and the mens rea was formed during the relevant time (see concurrence). Whether realistically or not, the officer apprehended the possibility of injury so the offence was complete. In R v Ireland, it was found that causing a person to apprehend violence can be committed by way of action or words. Words can also mean that otherwise threatening actions are rendered not capable of being an assault, as in the case of Tuberville v Savage. In that case, the plaintiff told the defendant (while putting his hand on his sword) that he would not stab him, because the circuit judge was visiting town for the local assizes. On that basis, the defendant was deemed to have known that he was not about to be injured, and it was held that no assault had been committed by the plaintiff (which would otherwise have justified the defendant's allegedly pre-emptive strike). The "immediacy" requirement has been the subject of some debate. The leading case, again, is R v Ireland. Therein, the House of Lords held that the making of silent telephone calls could amount to an assault if it caused the victim to believe that physical violence might be used against
