Missing: One golden cookie, weighing around 44 pounds (20 kilograms).

NOW YOU SEE IT...The combo photo released by Police in Hannover, northern Germany, Tuesday, Jan. 29, 2013 shows a statue gracing the façade of German cookie baker Bahlsen’s Hannover office before and after the rectangular gilded bronze sculpture was taken away.Suspect: The Cookie Monster?   

The rectangular gilded bronze sculpture was part of a statue gracing the façade of German cookie baker Bahlsen’s Hannover office.

How the century-old symbol was taken remains unclear, but police say witnesses reported having seen two men with a ladder in the area earlier that month.

The company has offered €1,000 ($1,350) for information leading to the cookie’s recovery.

A police statement said a local newspaper received a picture showing someone in an outfit similar to Sesame Street’s Cookie Monster holding a golden cookie.

The sender wrote to demand cookies be delivered to children at a city hospital.

Police aren’t sure if it’s the same cookie, or a real claim of responsibility.

Police now say someone dressed as the Cookie Monster has sent a second note regarding a stolen cookie sculpture — this time saying he wants to return it.

But officials aren’t sure the person in the photo actually stole the 20-kilogram (44 pound), century-old sculpture.

The Hannover police’s statement says a local newspaper received a picture of someone dressed like the Sesame Street character holding what appears to be the stolen cookie.

The enclosed note was written with cut-out letters.

German police have recovered a cookie sculpture that may have been stolen by someone impersonating the Cookie Monster.

Spokeswoman Jacobe Heers says the 20-kilogram (44 pound) gilded sculpture was found Tuesday morning, February 5, outside a university. It was hanging from the neck of a horse sculpture with a red ribbon.

The century-old cookie was reported stolen in January from the office of a bakery company in Hannover.

A local newspaper later received a letter demanding cookies be delivered to children at a hospital. The paper also received a picture of someone dressed like Sesame Street’s Cookie Monster holding what appeared to be the stolen cookie.

The Bahlsen company promised a reward of 52,000 packets of cookies for a charitable cause if their emblem turned up.

No suspect has been apprehended.
