Indian police are consulting with anthropologists to determine whether they can recover the body of American missionary Jonothan Chau after he was killed by the isolated Adaman tribespeople on North Sentinel Island.

Police expect an opportunity to arise when the tribespeople dig up the body and hang it from bamboo poles overlooking the Indian ocean, as they did in the case of two fishermen who trespassed in 2006.

A criminal case has been registered against the unknown tribesman who killed Mr Chau, but it is unlikely to be pursued as the Indian government has a strict hands-off policy.
