Australian Federal Police have arrested the captain and chief officer of a Chinese coal ship which ran aground on the Great Barrier Reef. The captain has been charged with liability for damage to a marine park. Officials say the ship leaked tonnes of oil and caused extensive damaged to the fragile coral of the marine reserve. The men face large fines and up to three years in prison if found guilty. Police said the two Chinese men would appear in court in Gladstone tomorrow. The bulk carrier is believed to have been taking an illegal shortcut when it ran aground on April 3 on its way to China from the port of Gladstone in Queensland.
