Officials at Hong Kong International Airport have uncovered 11kg of suspected cocaine hidden in the cushions of an electric wheelchair.
The haul, worth an estimated $1.5m (£1.26m), was found when a 51-year-old man was going through customs clearance on Saturday.
The man, who arrived from the Caribbean country of Sint Maarten via Paris on Saturday, has been arrested.
He could face life in prison if found guilty of trafficking a dangerous drug.
According to customs officials, the suspect brought the wheelchair into the country as one of two pieces of checked baggage.
Further examination was ordered when staff became suspicious and they found evidence that its seat cushion and backrest had been re-stitched.
The man, who is not from Hong Kong and has mobility issues, reportedly told officials that he was the director of a car rental company and that the wheelchair had been loaned to him by a friend.
