SAO PAULO (REUTERS) - Brazilian police said on Sunday (July 28) that they arrested one person and are seeking an arrest warrant for another in connection with the theft of a gold shipment at Sao Paulo's international airport last Thursday.

The authorities did not name any of the suspects in the theft, which involved 718.9kg of gold worth an estimated US$29 million (S$40 million) from the cargo terminal of Guarulhos international airport.

Security firm Brink's Co, which was responsible for delivering the gold to the airport, said in a statement last week that it had completed the delivery and the airline had full custody of the shipment at the time of the robbery.

Police originally believed the theft involved 750kg of gold and other precious metals, worth US$40 million.
