An 18-year-old man was arrested Tuesday on charges connected to assaults on police officers in the July 4 Fountain Square attacks.
Orlando Thomas is held without bond at the Hamilton County jail on one count each of aggravated riot and inducing panic.
He is scheduled to be arraigned at 9 a.m. Wednesday before Hamilton County Common Pleas Court Judge Megan Shanahan.
Thomas was indicted last week along with several others involved in the melee as a rap concert ended about 11 p.m . on Fountain Square.
Only eight officers were patrolling the area when people began hurling bottles and fireworks at police. About 60 officers, some in riot gear, responded.
Officer Roger Noe and Officer Joe Simpson were struck in the face.
Facebook videos surfaced showing a man, Christopher McKnight, beaten and bloody on the pavement. McKnight was knocked unconscious and suffered a broken nose with several abrasions and bruises.
Cincinnati Police Chief Jeffrey Blackwell asked Hamilton County Prosecutor Joe Deters to consider hate crime charges, but Deters said there was no evidence the attack as racially motivated.
Mordecia Black, 28, Raeshaun Hand, 19, and Steven Montgomery, 18, face charges of felonious assault, aggravated riot and inducing panic in connection with McKnight's beating. A juvenile is also charged.
Jy Quynn Britten, 21, and a juvenile suspect are charged with assaulting the officers. Thomas, Gary Sheffield, 29, and Tyre Burke, 18, were indicted on aggravated riot and inducing panic in connection to the officers' assault.
The Saturday night hip hop series at Fountain Square has been booked and promoted by Self-Diploma and 3CDC for the past five years.
This year's series was originally slated to run until September, but it was canceled after the attacks.
