Police in Indonesia said they were investigating the teenager as he was likely drowned. “We believe there is a high probability that he will no longer be in Malaysian waters based on the movement of the sea currents, as well as the time and location where the other victims were found,” Mersing District Police Chief Cyril Edward Nuing told reporters. . Malaysia’s assets will be on hand to help, he said. Ms Grodem earlier told officials the team showed up about an hour after it sank on Wednesday but could not find their boat. He was later separated from the others after being caught in strong currents. The pilot of the boat that took them to the dive site was arrested after he tested positive for drugs, police said.
