Radioactive monitoring devices used for the first time

Team effort: The joint operation between various agencies was aimed at nabbing foreigners suspected of having links to international terror groups or illegal activities, and those without valid documents.

KUALA LUMPUR: The massive counter-terrorism swoop in the city centre marked the first time radioactive monitoring devices were used in such an operation.

Atomic Energy Licensing Board technical officer Mohd Irwan Effendi Mohd Nordin, who was on the ground during yesterday’s joint raids, said his department provided three types of monitoring devices for the operation.
