Mexican authorities have uncovered a new method of drug smuggling after two men were found in a container with cocaine on an AP Moller-Maersk boxship.

The two men appeared to be dockworkers, reports said this week after the 9,640-teu Maersk Svendborg (built 1998) was raided at Manzanillo on 2 July.

The CE Noticias Financieras website said a probe by the Attorney General's Office and Semar, the federal government's marine secretariat, indicated the pair posed as port company employees to gain access to the vessel.
