More than 2,000 evacuated as wartime bomb unearthed in Happy Valley

A 2,000-pound unexploded US wartime bomb was unearthed on a Happy Valley construction site yesterday, sparking the evacuation of more than 2,000 people from nearby hotels, offices and flats.

Early this morning a police bomb disposal team was working to dismantle the device - an AN-M66, which contained 450kg of explosives. The bomb was the biggest of its kind dropped on Hong Kong by US bombers during the Japanese occupation of the city in the second world war.

Moving the bomb from the construction site was not an option due to the risk of triggering a huge explosion.

Police and fire officers were called to the site in Hau Tak Lane, near the racecourse, when a worker discovered the bomb during excavation work at about 3.45pm. An area within a 200-metre radius was cleared.

A senior bomb disposal officer, Jimmy Yuen Hon-Wing, of the Explosive Ordnance Disposal Bureau, said a US bomber flying out of Guangzhou had carried the bomb and that it must have landed on soft ground and failed to detonate.
