Chicago Bears receiver Devin Hester was slapped on the back of the head at a Des Plaines, Ill., casino on Friday by a man who was arrested on a misdemeanor count of battery, Des Plaines Police Chief Jim Prandini said.

Daniel Rago, 52, of Mount Prospect, Ill., was charged after slapping the back of Hester's head while the receiver was in a cash transaction line Friday night.

"Rago comes up from behind and slaps Mr. Hester with an open hand and walks away," Prandini said Tuesday. "Mr. Hester turned around and notified casino security. The offender was escorted to a security office and we were contacted. We were able to review the incident on video, and that verified the facts as stated by Mr. Hester.

"No prior incident between the two took place."

Prandini did not believe that Rago knew who he was slapping. He said Rago made some type of statement about "slapping the hat off his head or something."

Hester cooperated with officers and signed a complaint.

Rago has a Dec. 1 court date.

Hester scored two touchdowns during the Bears' 39-10 win over the Minnesota Vikings on Sunday night. He also sustained a chest injury and left the game in the fourth quarter.
