Two horses shared a truck travelling from Europe to Britain with hidden cocaine worth more than £3 million, authorities report.
The 80 kilograms of cocaine was found in the horse truck at Harwich International Port by staff with Britain’s Border Force agency.
The horse truck had arrived on a ferry from the Hook of Holland, a town in the southwest of the Netherlands. It carried two horses, the agency said.
A scan of the truck revealed a cavity in an internal wall, which was drilled to allow an inspection which revealed the cocaine.
Both horses were placed in the care of a local equine charity.
The seizure on March 26 sparked a National Crime Agency inquiry.
A Hungarian man, aged 32, and two German women, aged 42 and 50, have been arrested and bailed as inquiries continue.
The regional director for Border Force, Phillip Holliday, described it as an unusual and well-hidden concealment.
He said the vigilance of the agency’s officers had foiled an attempt to smuggle a large amount of the Class A drugs into Britain.
“Working with law enforcement colleagues like the National Crime Agency, we are determined to prevent drug trafficking and put those responsible behind bars,” he said.
