BERLIN -- A German postal worker admitted to putting packages up for auction over the Internet after a search of his apartment turned up a hoard of missing deliveries, police said Thursday.

The 37-year-old letter carrier, whose identity wasn't released, started siphoning off packages and offering their contents on online auction site eBay last summer, police said. In all, more than 100 went missing, and police estimated the total value at $23,700.

While the German post office noticed that packages frequently went missing on his round, it was unable to prove anything until a musician whose clarinet mouthpiece went missing in the mail blew the whistle.
