Lunch at a restaurant proved costly for a garment merchant whose business and marriage suffered after he was arrested on unfounded allegations, a writ says. Leung Wai-keung entered Wonderland Sea Food Restaurant in Shekkipmei Estate to have lunch with friends on June 3. But restaurant owner Yuen Wing-hong called the police, accusing the 'usual customer' of blackmail and criminal damage, according to the writ. He was handcuffed and removed from the ground-floor premises by plain-clothes officers. Mr Leung says in the High Court writ that the complaint was found to be unfounded. He is suing Mr Yuen for more than $500,000. Mr Leung says the incident forced him to shut his garment factory in Dongguan, Guangdong, and the amount sought is to cover losses sustained through the closure. He was released by police without any conditions, but he has not been able to pay his former workers, the writ says. 'The plaintiff then suffered stress and anxiety and could not calm down,' the writ says. Further, Mr Leung's 'mutual trust' with his wife was 'totally impaired' over Mr Yuen's allegations. He also alleges he was assaulted by one of the arresting officers at Shekkipmei police station, suffering injuries to his forehead and chest. Mr Yuen is named as the sole defendant in the writ, which also seeks other unspecified relief.
