Hong Kong's explosive disposal unit has successfully defused a suspected World War II-- - era bomb found in a 'dangerous condition' at a construction site in city's center, police said. It is the second unexploded device to be unearthed in the Chinese territory in a week.

Bomb disposal officer Alick McWhirter said 'The bomb is in a dangerous condition, the fuse mechanism is severely damaged and the position of the bomb is making it difficult for our equipment to gain optimal access.'

Police said about 4,000 people were evacuated from the immediate area during the operation and some cross-harbor ferry services were also suspended.
