POLICE will buy another bomb disposal robot next year to replace the existing machines too bulky to handle certain assignments. The first such robot, called Cyclops, was used to destroy a suspected device after a bank robbery in Central four days after its delivery in November. Senior Superintendent John Rolison, Senior Force Bomb Disposal Officer, said the Cyclops was smaller than the five other existing bomb disposal machines. He said although the five old ones still functioned properly, ''they are a bit large for various jobs we might want to do such as a package on MTR trains or package on an aircraft''. Mr Rolison said Cyclops could be controlled by radio signal or through an optic cable, while the old machines could only be controlled through a wire cable. He said the Cyclops cost about $400,000, which might be considered costly. ''But what you have to consider is that if a bomb goes off inside a building, the damage it will cause goes into millions of dollars,'' he said. Mr Rolison said the Cyclops could fire a water cannon to destroy the circuit of a bomb.
