Caught in a "delirium of hormones," as a police statement on Monday put it, the two boys got only a tenth of the value of the jewels when they sold them to a canny gold dealer.
"With their proceeds of €300, the pair didn't just buy pizza, kebabs, and have a game on the fruit machines," police spokesman Ralf Minet said. They also paid two visits to a brothel in the red light district of Karlsruhe, southwest Germany.
Buoyed by the night's experiences, “one could still see a delighted smile on the faces of the thieves during their interrogation," Minet's statement said.
"But the little rascals' smiles, who are not unknown to the police by the way, disappeared soon enough, especially because they will have to pay for the reversal of the transaction out of their pocket money," he added.
The boys are to be charged for theft.
