A HOMEMADE bomb was placed inside a crowded Jockey Club off-course betting centre in Tai Wai, Sha Tin, last night.
A security guard at the Yan Ping Building centre picked up a plastic bag containing two tins when they started emitting smoke at 10.05 pm, shortly before the last race at Happy Valley.
Police said the Jockey Club headquarters in Happy Valley had received a telephone call at 9.30 from a man who said a bomb would be left in the Tai Wai centre.
He said a man would cash in two tickets before disclosing where the bomb could be found.
The centre was not cleared until after the guard picked up the bag from near the information counter and carried it to a lane behind the building.
It was not clear whether the guard was aware of the warning. He told his superiors about the bag and they called police.
Police bomb disposal officer R.C. Holland described the device as a crude home-made bomb.
Residents in the six-storey building above the betting centre were told to remain inside while the package was detonated.
Mr Holland found electrical wiring, batteries and a small quantity of thinner in the tins. He also smelled gunpowder.
