Dubai Police has seized more than 5 tonnes of the amphetamine Captagon.

The operation has been hailed as one of the biggest drug busts ever recorded in the country and resulted in four arrests.

Officers were able to track two lorries carrying more than 3.5 million pills as they were driven to Sharjah.

The haul was concealed inside large drums used to transport electric cables.

“The operation was against one of the largest Captagon drug rings in the world,” said Maj Gen Abdullah Al Merri, commander of Dubai Police.

“It resulted in the arrest of four people who are part of an international drug-smuggling gang directed by a leader based in a Eurasian country.”
