Determined to bring Christianity to a tribe that has shunned contact with the rest of the world, American missionary John Allen Chau was reportedly killed by the Sentinelese when he landed on their shores in November, in a story that has travelled across the world.

In a lesser-known encounter on Jan 4, 1991, two boats with outsiders drifted close to the island inhabited by the Sentinelese, to a location that today seems ironically named - Allen Point.
