The Sydney native wore only his shoes and held his underwear in his hand during the chase in freezing temperatures, a spokesman for the Bavarian state police said. The teenager quickly changed into his underwear once he fell and police later covered him in a blanket.

During questioning the teenager told police that he was carrying out a bet with friends that he could travel through Europe naked. The Bavarian capital was the 11th city on his tour and the first in which he was caught out, according to police. "I simply like to be naked," the police spokesman quoted him as saying.

The Australian teenager was fined 100 euros ($132).
