Police are trying to determine the source of fireworks seized in one of the largest hauls of the illegal goods in Hong Kong. The haul - in the northern New Territories on Wednesday - was part of a police campaign targeting smuggled fireworks in the run-up to the Lunar New Year. Officers reported confiscating 202.5kg of fireworks, in the form of so-called 'coconut' firecrackers. The fireworks were found inside an abandoned light-goods vehicle in an open space in Pat Heung, Yuen Long. Police spotted the vehicle about 11pm on Wednesday. On further inspection, officers found 629 coconut fireworks. Police estimated the haul could fetch about $45,950 in the marketplace. It is believed that the seizure was one of the biggest last year. No one has been arrested and police are still trying to find out who owns the fireworks and how they were smuggled into the city. The seized fireworks have all been taken to the Pat Heung police station, pending further examination by experts. Coconut fireworks - so named because of the appearance of the spherical, 15cm diameter devices - are extremely powerful and can cause fatalities within a one-metre radius of detonation. They have been known to cause damage to buildings in a five-metre radius.
