Odell Beckham Jr. will not face charges for slapping a security guard on the butt in the locker room after LSU's 42-25 win over Clemson in the College Football Playoff National Championship on Monday.
"This legal matter has been resolved," Davillier said.
The Orleans Parish District Attorney's office also said it would not pursue the case.
The security officer was in LSU's locker room talking to offensive lineman Damien Lewis when Beckham gave the officer a slap on the backside.
"We are aware of the incident and have been in touch with Odell and his representatives on the matter," the Browns said in a statement. "They are cooperating with the proper authorities to appropriately address the situation."
Beckham was in New Orleans to support LSU, where he played for three seasons from 2011-13.
