Justin Bieber's not the only 17-year-old donating DNA to settle a worldwide controversy.

The Forest Boy, who answers to the name “Ray” and claims he spent five years living in the Czechoslovakian wilderness, will give his DNA to officials in Germany in a bid to locate his relatives, Mirror UK reported.

It's a change of pace for the teen, who initially refused to supply a DNA sample after a Swiss couple stepped forward and told officials they were his grandparents.

German police said a number of key factors have led them to determine the tale of Forest Boy -- the 17-year-old who claims he spent five years living in the Czechoslovakian wilderness -- is false. 

As we previously reported, the boy -- who is believed to be 17 years old and answers to the name “Ray” -- sprouted up at Berlin City Hall in Germany September 5, claiming he'd surfaced from the woods (on the Czechoslovakian side of the Ore mountains) after camping out there for five years with his father, who recently died.

The blond-haired, blue-eyed lad claims his late father, who he identified as “Ryan,” took him to live in the woods following the auto accident death of his mother, Doreen. He said that following his dad’s death, he began his trek toward civilization. When he finally arrived at city hall, he reportedly told officials: "I'm alone in the world. I don't know who I am. Please help me."

The forest boy mystery is deepening, and some serious doubt is being shed over the story spun by the lonesome teen.

A couple from Switzerland has come forward claiming that Forest Boy is their grandson and have agreed to submit a DNA sample to prove there is a genetic link to that of the mysterious teenager, according to Berlin's B.Z. newspaper.

As we previously reported, the boy -- who is believed to be 17 years old and answers to the name Ray -- purportedly spent five years living in the wilderness before sprouting up at Berlin City Hall in Germany September 5, following what he claims was his father's death.

The baffling story of a teenage boy claiming to have lived in the wilderness for five years has made headlines around the globe.

The 17-year-old - who answers to the name Ray - presented himself to authorities in Berlin insisting he had been surviving in the forest with his dad since a car crash that killed his mother half a decade ago.

But three weeks have passed since Forest Boy - as he has been dubbed - arrived on the steps of City Hall and begged for help and his bizarre case is still shrouded in mystery.

Ray claims he only came back to civilization after his dad died in a fall a few weeks ago.

He says he buried his father then followed his compass back to the German capital a distance estimated at an incredible 150 miles.

But other than his first name, his date of birth and the fact that he speaks fluent English, very little else is known.

As RadarOnline.com previously reported, despite his alleged wild upbringing, Ray is surprisingly civilized and has been adapting to modern life well.

According to Beate Kohn, a hostel worker, where Ray was staying, he has table manners, showers regularly and likes bowling and watching TV.

"He was very, very kindly to everybody, with the other kids and with us," said Kohn, 50 who admitted that he "had moments where he appeared uneasy, but generally he settled in well and appeared comfortable."

This is indeed shocking for a boy who has been starved of human contact for so long.

"We have cases where it is obvious what has happened, and cases where there are a lot of questions,’ said Kohn.

"Obviously, in his case, there are a lot of questions. He may have seemed quite normal, but if you have suffered a significant trauma that can happen. You have to find out the story behind the trauma."

Some think the boy is originally from England due to his dialect, but he is believed to have inhabited the Czechoslovakian side of the Ore mountains during his time in the wild.

Interpol have failed to match the boy with any missing person and police are refusing to release an official photograph of Ray until a guardian has been appointed.
