Lim grabbed Lau by the shirt collar and frog-marched him to the office in order to avoid further trouble after Lau shouted threats at Seow. This action by Lim potentially constitutes a battery against Lau as it involves the intentional application of physical force. Later, Lim asked friends Chong and Cheng to ensure Lau did not leave the office, which could constitute false imprisonment if Lau was unaware of their presence and unable to leave freely for four hours. Overall, the facts reveal possible causes of action for battery by Lim against Lau and false imprisonment by Chong and Cheng against Lau.
