Spanish authorities have found more cocaine hidden in the hold of a general cargoship that was at the centre of a drugs bust in Brazil three weeks ago.

A further 1,200 kg of the drug was discovered in millet on the 9,800-dwt Unispirit (built 2006) at Las Palmas in the Canary Islands, La Provincia reported.

The vessel docked at the Santa Catalina dock last week.
