Robin van Helsum, in his early 20s, gained fame in 2011 when he entered Berlin's City Hall and claimed to be "Ray," a dweller in a nearby forest. He said he did not know his last name, and had lived in the wilderness since his father's death in a fall, NBC News reported.
His story was uncovered as a hoax after his photograph appeared in European media. A woman in the Netherlands contacted police in 2012 to report "Forest Boy" was her stepson, who disappeared the previous year.
A legal settlement was arranged Thursday during his trial for fraud, in which prosecutors demanded van Helsum return approximately 30,000 euros ($40,445) he received from German youth organizations.
Court spokesman Tobias Kaehne said van Helsum could have received a similar amount in government benefits as a homeless adult, and thus would not be ordered to make financial restitution.
"The loss to the taxpayer is either nothing or very small," Kaehne said.
