TROY - Another Uncle Sam has lost his head.

It appears vandals have discovered a weak spot on the 30 statues that make up a public art installation on sidewalks in front of businesses is various spots downtown: This is the third fiberglass exhibit to be damaged in this fashion in recent weeks.

Staff at Bruegger's Bagel Bakery on Congress Street reported at 6:30 a.m. Thursday that the head was "forcibly removed" from the statue, Police Capt. John Cooney said.

At least this Uncle Sam head was found; the head of a multicolored likeness of the top-hatted American icon anchored on Fourth Street has not been discovered.

Patrol officers found that statue beheaded around 3:40 a.m. Saturday. Police have no leads on the culprit or culprits in either case of vandalism, Cooney said.

Officials are asking business owners to check their video security cameras to see if the act was captured.

Former Mayor Harry Tutunjian and his wife, Francesca, the owner Francesca's Cafe on Broadway, offered $100 for information on the culprits, and for the return of the head. That reward has now grown to several hundred dollars.

The Bruegger's-area statue was repaired Thursday at the Downtown Troy BID office on River Street.
