The International Maritime Bureau has issued an alert for ships travelling near Indonesia's Mangkai Island in the South China Sea following a trio of attacks in as many days by what the IMB believes to be the same gang of 5-8 pirates armed with long knives and batons. In the most serious incident, the group tied up the master, second officer and a third crewman on watch duty on board the 12,300 dwt LPG carrier Sigloo Discovery before robbing them.
