ROCKFORD (WIFR) -- Rockford police are investigating an attempted robbery at Denny's.

Police say around 5:00 p.m. Monday, officers were called to the Denny's on East State Street. Workers at the restaurant say a white man around 45-years-old came into the restaurant, ordered food, ate and when given his check, he wrote a note on the back saying this was a robbery and he had a gun.

No gun was displayed, no shots were fired and no one was hurt.

The suspect is described as a white man, 45-years-old, with white hair and a full beard. Wearing a possible yellow shirt and blue jeans. Anyone with information is encouraged to call police at 815-987-5824 or CrimeStoppers at 815-963-7867.
