Police have warned villagers they will show zero tolerance towards illegal fireworks during Lunar New Year celebrations. The warning came after the seizure of 427kg of fireworks and the arrest of seven people so far this month. David Thomas, acting regional commander of New Territories North, said police would be tough on offenders. 'What I mean by zero tolerance is simply this: those involved will be arrested and charged accordingly,' he said. Those facing prosecution this year so far include a woman, 53, allegedly found in possession of 50kg of fireworks at her store in Shek Po Lam Tsuen, Tin Shui Wai, yesterday. Earlier this month, five men were arrested in Aberdeen allegedly smuggling 377kg of fireworks. Police said if the fireworks had exploded they could have killed people within a 10-metre radius and damaged buildings within 20 metres. Ip Suen, deputy police commander of the region, said the potential dangers of fireworks had become greater in recent years as they had been modified by their mainland manufacturers. '[A firework] could kill easily. Last year, a Guangdong man was almost blown up by the so-called 'coconut head' fireworks,' he said. Police have already intensified their crackdown on all fronts including smuggling, storage, distribution, and retailing of fireworks. Intelligence about the smuggling would also be shared with mainland police. Mr Suen said police would co-operate with rural committees in publicity campaigns against illegal fireworks. The northern New Territories is a fireworks blackspot. Last year 35 people were arrested in the district and 2,189kg of fireworks were seized.
