While sailing under pilot at Guayaquil River in Ecuador, a group of perpetrators boarded 'Maersk Newbury'. The master notified the local authorities when he saw unauthorised persons on board.
The perpetrators assaulted one of the crew and sustained a small cut on his forehead. Luckily, all of the crewmembers managed to escape and hide in the forecastle store. There was no injury to the remaining crew and no items were stolen.
The perpetrators left the ship when they realised that they had been discovered.
A little later the Ecuador Coast Guard (ECG) conducted a search on the ship and no perpetrator was found. The injured crew was given first-aid treatment, and the ship continued its voyage.
