Ten people, including a number of leading restaurateurs, have been arrested in Galicia accused of selling contaminated scallops illegally harvested from Ferrol's busy port estuary. It is believed that the shellfish are contaminated with a dangerous toxin that can cause memory loss. A source close to the investigation, which is being handled by a judge from Ferrol municipal court, refused to rule out further arrests, and was unable to confirm rumours that celebrity chef, Toñi Vicente, is among those detained.
