BERLIN -- Police in Berlin were investigating Friday after an English-speaking teenager walked out of a forest, claiming to have lived in the wild for five years with his father, The Local reported.

Officers launched an appeal for information about the boy -- who is aged between 16 and 18 -- following his arrival in Berlin on Sept. 5.

The boy, who said his name was Ray, told authorities that he went into the wild with his father, Ryan, after the death of his mother. They lived in a forest near Berlin and slept in a tent or huts they found in the wild.

Two weeks ago, Ray said, his father died and he buried him in a shallow grave which he covered in stones. He then began to walk north and after two weeks reached Berlin.

The boy speaks English fluently but has little facility with German.

"We have sent appeals for help to all European countries via Interpol. The boy speaks English and a little German but we really have no idea where he comes from," Berlin police spokesman Michael Maass told The Local.

"His father had told him to look at his compass and go north, if anything should happen. And this is apparently what he did, walking for two weeks before reaching Berlin. We have no evidence to contradict what he has told our colleagues ... although we are still investigating, and very much want to find out who he is," he added.
