With the summer holidays just around the corner, a customs spokesman reminded members of the public, in particular younger people, that criminals might post recruitment advertisements on unknown websites and social media platforms to lure students and young people into carrying dangerous drugs or various controlled items.
"They are reminded to stay alert and not to carry unknown items for other people," the spokesman said.
He said customs officers would continue stringent law enforcement at every boundary control point.
A law enforcement source said drug dealers made offers of "quick cash" via online chat groups and they usually recruited their targets when they were added to chat groups by friends.
"They are offered free air tickets and accommodation in Asia and South America with rewards of up to tens of thousands of dollars to smuggle drugs into Hong Kong," he said.
In Hong Kong, trafficking in a dangerous drug carries a maximum penalty for a life imprisonment and a HK$5 million fine (NZ$970,000).
According to official statistics, local authorities seized 604kg of cocaine in 2018, up 174.5 per cent, compared with 220kg in 2017. Seizure of methamphetamine, also known as Ice, also rose by 149 per cent to 359kg in 2018.
