Police subsequently arrested seven fishermen for assisting Chau to get close to the restricted island. His death was treated as a murder, but there was no suggestion that the Sentinelese would be charged and the U.S. government confirmed that it did not ask the Indian government to press charges against the tribe. Indian officials made several attempts to recover Chau's body but eventually abandoned those efforts. An anthropologist involved in the case told "The Guardian" that the risk of a dangerous clash between investigators and the islanders was too great to justify any further attempts. He remains buried on the island.
