John Chau, 27, was killed on North Sentinel Island in November after being struck by a bow and arrow.

Local fisherman reported seeing the tribe drag his body with a rope days after Chau paid them to take him as close as they would to the island.

His father Dr Patrick Chau has spoken out and said the American missionary community is responsible for his son's death.

He claimed John was an 'innocent child' who died from an 'extreme vision' of Christianity taken to its logical conclusion.

Like his son, Chau was a graduate of Oral Roberts, an evangelical university in Oklahoma. He told The Observer: 'If you have [anything] positive to say to me about religion. I do not wish to see or hear it.

John Chau, 27, was killed on North Sentinel island in North Sentinel Island where he was trying to convert a remote tribe to Christianity

'John is gone because the Western ideology overpowered my [Confucian] influence. He blamed evangelicals' 'extreme Christianity' for pushing his child into a 'not unexpected end'.

He also made reference to the 'great commission' which is the purported instruction from Jesus that Christians spread the gospel to all people.

Chau, who was born in Alabama but grew up in Vancouver, Washington, was consumed by two passions since childhood which were outdoor activity and Jesus Christ, the Observer notes.

It was reported that Chau, who attended Vancouver Christian High School, first read about the Sentinelese on a missionary database called the Joshua Project.

The Sentinelese are considered one of the Earth's last uncontacted tribes and they are believed to number just several dozen people.

Chau was killed by members of the Sentinelese people (some of whom are shown in an undated stock photograph) after approaching their island uninvited on a kayak

The Sentinelese attracted international attention in the wake of the 2004 Asian tsunami, when a member of the tribe was photographed on a beach, firing arrows at a helicopter (pictured)

They have been described as an 'extremely isolated' tribe and the Indian government have banned access to North Sentinel Island as they are thought to be extremely hostile towards outsiders.

The Sentinelese tribe live on North Sentinal Island, which lies around 450 miles from the coast of Thailand and more than 745 miles from mainland India

In October 2017, Chau began his missionary training at All Nations’ headquarters in Kansas City, The New York Times reported.

Chau visited the Andaman islands in 2015 and 2016, and had made contacts with a local evangelical before he departed.

He had traveled to the area to share the love of Jesus, friends had previously claimed.

He wanted to have a long-term relationship, and if possible, to be accepted by them and live amongst the tribe.

Chau had reported tried to prevent himself from getting sick to protect the islanders, who are vulnerable because their immune systems have not been exposed to a host of illnesses.

With the help of a local evangelical, Chau hired five fishermen and set out with them towards the island on November 14.

The family of John Chau released this statement as they begged for Indian police to release the seven men they have charged in relation to his death and not pursue charges against the tribe

Chau assembled a kayak because the fishermen refused to go to the island with him and insisted on staying a half mile out.

In a letter he wrote to his parents before he traveled to the island, Chau had recounted seeing some islanders on the beach.

He paddled up to them and tried to preach, saying: 'My name is John, I love you and Jesus loves you,' according to the note.

The islanders then chased Chau into the surf. He saw the fishermen far away, waving their arms up and down, and swam to them.

The fishermen told the police that the following morning Chau swam to the island.

They returned to North Sentinel the following day to check on Chao. It was then that they saw natives on the beach dragging his body with a rope.

All five fishermen were later arrested, along with two others and were accused of helping lead Chau to his death.

In the letter to his parents, he told them not to hold the tribe responsible for his death if he did not come back alive.

'You guys might think I'm crazy in all of this, but I think it's worth it to declare Jesus to these people,' he wrote.

In an Instagram post on his account in November, his parents Patrick and Lynda revealed they had forgiven the tribe and urged Indian authorities to release the local men who Chau paid to take him close to the island.

One of Chau's friends previously revealed to DailyMail.com that he was 'committed' to travelling to the remote island, deep in the Indian Ocean, to preach Christianity to the tribesmen and had been planning the trip for at least three years.

Neil MacLeod, of Stornaway, Scotland, said he met Chau on a flight from London to Phoenix, Arizona, in October 2015.

'I saw him reading some Christian literature and I'm a Christian and we started talking,' he said.

MacLeod, 47, said Chau told him he had recently returned from India and was trying to figure out how to travel to the remote North Sentinel Island in the Bay of Bengal.

'He mentioned that he wanted to go to these islands, the islands where he has now died,' MacLeod said. 'I had heard of these islands and I know how dangerous they are, so I was surprised by that.
