"The man who was arrested at Rivers Casino in Des Plaines after police said he slapped Chicago Bears receiver/returner Devin Hester in the back of the head has apologized.

Hester was in a cash transaction line at around 10:40 p.m. Friday when Daniel Rago, 52, approached him, slapped him in the back of the head and walked away, Des Plaines Police Chief Jim Prandini said. Hester notified the casino's security team and Rago, a Mount Prospect resident, was escorted to a holding area and later arrested by Des Plaines police."
