Are you aware of the law?
Trespass to the person
The general principle is that a trespass to the person must be a direct and intentional act, while if it was indirect or unintentional the tort of
negligence is more appropriate, as established in
Letang v Cooper. The tort of trespass to the person contains three possible types; assault, battery and false imprisonment.
Assault
In English law, an assault means to act in such a way that the claimant or victim apprehends the application of immediate unlawful force upon themselves. The key elements of the tort are therefore that the defendant acts, and does so in such a way that the claimant is put in fear of "immediate physical violence". There is no requirement that actual damage be caused. In
R v Costanza, the courts held that threats made by a stalker could be assault, while in
R v Ireland, the
House of Lords said that in the right situation (specifically, harassing phone calls) silence could be enough. In some situations an act which would otherwise be assault can be mitigated by the language used. In
Tuberville v Savage, the defendant reached for his sword and told the claimant that "if it were not [court] time, I would not take such language from you"; it was held that despite the threatening gesture, this meant the claimant was not in immediate danger. The actions must give the claimant reasonable expectation that the defendant is going to use violence; if a fist was raised in front of the claimant, it could be enough. If the fist was raised from inside a police van following arrest, it would not.
Battery
Battery is defined as "the intentional and direct application of force to another person", and has three elements; force, direct application and intent. The courts have also added a requirement of "hostility" or lack of consent in many cases.
As with assault, there is no need to show that damage was caused. Any application of physical contact, regardless of harm caused, can constitute force. In
Collins v Wilcock, a female police officer took hold of a woman's arm, intending to talk to her on suspicion of soliciting contrary to the
Street Offences Act 1959. The woman scratched the female police officer's arm. As the female police officer had gone beyond her duties in grabbing the woman (since she did not intend to charge her with an offence, but was still using force) it was held that this constituted "force".
Goff LJ wrote that the fundamental principle is that any person's body is inviolate, except in situations where the bodily contact "[falls] within a general exception embracing all physical contact which is generally acceptable in the ordinary conduct of daily life".
Report it to the Police, and tell them that you want to press charges. It is basically an assault on a minor. DO NOT let them fob you off.
