THOMAS (1985) - School care taker took hold of a girls skirt. Touching clothing is the same as touching the person so would amount to battery
DPP v K (1900) - Defendant put acid in hand drier so the next person to use it was sprayed with acid. An indirect action can be the actus reus of battery.
COLLINS v WILCOCK (1984) - A police officer held a woman's arm to prevent her walking away. Any touching may be a battery, and always is if there was physical restraint.
