ABC News' Roberto Valussi reports:

It's the end of the captivity for the 20kg golden biscuit, trademark of the German sweet company Bahlsen, which was kidnapped by a self-styled Cookie Monster last month.

The biscuit was found Tuesday with a red ribbon, tied up, hanging from a horse statue in the town of Hanover, north Germany.

The identity of the criminal remains unknown and well disguised under the form of the character of Sesame Street.

He claimed credit for the kidnapping by contacting a local newspaper with an old-fashion blackmail letter compiled of different words from separate printed articles. The Cookie Monster required the company to distribute biscuits to all of the rooms in the local children's hospital.

If his demands were not met, the criminal ensured the biscuit would "wind up in the trash with Oscar the Grouch. "

The letter was also accompanied by a picture of him, dressed up as the blue Cookie Monster biting the golden biscuit.

From his Twitter account, the original Cookie Monster felt compelled to announce: "Me no steal the golden cookie. But me willing to help find real cookie thief!"

The reactions from within the Bahlsen company - the producer of the internationally successful Leibniz brand of cookies - were mixed.

It declared that it "refused to be blackmailed" and offered a $1,350 reward for information leading to the cookie's recovery. It also promised to donate 52,000 packs of biscuits to different social organizations.

While the police were still hunting, the deviant Cookie Monster announced in a second letter that "because Werni [Bahlsen CEO Werner Bahlsen] loves the biscuit as much as I do and now always cries and misses the biscuit so badly, I'm giving it back to him!"

The day after the publishing of the second letter, the biscuit was found hung around the horse's neck.
