New Zealand police say they have made their biggest ever seizure of cocaine, hidden inside a novel kind of drug mule.
An American and two Mexicans were arrested over the weekend following a six-week investigation. The horse's head weighed 365kg and was 1m (3ft) tall, the New Zealand Herald reported.
"This is a significant win for New Zealand," said Det Supt Virginia Le Bas. "We should proud to have detected it at the earliest of stages."
