An elderly man who was locked up for 10 hours then placed on a good behaviour bond after trying to stop a hygiene officer from arresting a hawker says he doesn't regret what he did but wouldn't do it again. 'It was an awful experience,' Tsui Wai, 70, said after appearing in Kwun Tong Court yesterday. 'I was a prisoner for 10 hours for something I did out of sympathy.' The retiree was acquitted in Kwun Tong Court of one count of obstructing a public officer and one of common assault on assistant hawker control officer Chung Leung-yau after the prosecution decided not to offer evidence against him. Acting Principal Magistrate Abu Bakar bin Wahab placed Tsui on a HK$2,000 bond for nine months during which time he must not use violence or obstruct a public officer. The court heard Tsui pushed Chung to the ground as officers were trying to arrest a 74-year-old woman for illegally selling medicated Chinese wine on Yee On Street, Ngau Tau Kok. Outside court, Tsui said he had acted on the spur of the moment when he saw the woman surrounded by the officers. 'I didn't do it for my benefit. I was just passing by and saw the hawker on one knee with her other leg bandaged up. I did it out of sympathy,' he said. 'It was way over the top - there were seven or eight huge officers surrounding a 70-something old lady. I do not regret a thing but I will pretend I see nothing next time I see something like that.' Tsui said he intervened when he saw the officer seize the hawker's suitcase. He said he asked the officers to give the hawker a chance and told the hawker to leave because the officers had their job to do. 'I put my hand between the officer and the hawker to separate them. I didn't do anything but the officer somehow fell to the ground,' Tsui said. 'There were lots of people looking on. They also tried to persuade the officers not to arrest the hawker but they just ignored the pleas.' He suggested the officers were making a selective prosecution. 'There were lots of telecom salesmen in the street and they did not arrest them,' he said. Tsui said there was a bright side. 'It made me a famous person. I am better known than [pop star] Leon Lai,' he said as he was mobbed by reporters and looked at by passers-by. The Food and Environmental Hygiene Department said it was studying whether its frontline officers had breached working guidelines when arresting the elderly woman for illegal hawking. It had not yet decided whether to press a charge against the hawker, who suffers from cataracts.
