The estimated street value of the drugs was S$118,000, CNB said, adding that the Ice and cannabis seized could have fed the addictions of about 310 abusers for a week.
Investigations are ongoing.
“The operation on Mar 13 is an example of the dangers that our officers face every day,” said Superintendent Stanley Seah, the deputy director of CNB’s Intelligence Division.
“Drug traffickers may be armed, increasing the risk to our officers. But this will not deter us.
“CNB officers will remain steadfast in our efforts to prevent drugs from flowing to the streets.”
Those found guilty of trafficking more than 250g of methamphetamine or 500g of cannabis may face the death penalty.
