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 wilderness boy making headlines out of Germany might have walked an amazing 150 miles through the woods before he touched concrete, RadarOnline.com has learned.

The boy, believed to have inhabited the Czechoslovakian side of the Ore mountains, "would have walked all the way to Berlin from the Czech Republic," a source close to the situation said. "This would have been a much harder prospect than simply walking from woods south of Berlin, which is what many believed he had done up until now."
