Colombian police have discovered cocaine hidden in the engine room of a bulker in Barranquilla.

A total of 87kg of the drug was found in 91 packages on the 34,000-dwt OMM-managed Nord Manzanillo (built 2010), the Caracol website said.

There is no suggestion of crew involvement.

The ship was due to head for Trinidad & Tobago with coal.

No arrests have yet been made.
