Customs officers have arrested five men at the airport for smuggling cannabis and cocaine worth $1.12 million into Hong Kong.

On April 25 officers stopped four men arriving from India. They found 4kg of cannabis resin worth $288,000 concealed in men's shoes.

The next day they inspected a man arriving from Ethiopia and found 1.47kg of cocaine worth $830,000 inside a concealed compartment in a suitcase.

The five cases bring the total drug-smuggling detections at the airport since March 26, to 13.
