CLEVELAND, Ohio-- Six inmates, including one accused of participating in a shooting that killed a 12-year-old boy and injured five teenagers, face new charges in connection with a riot at the Cuyahoga County Juvenile Detention Center.

The teens-- one 14 and the rest 15 -- are charged with aggravated rioting, inciting violence, disorderly conduct and vandalism, Cuyahoga County Prosecutor Michael O'Malley said at a news conference on Thursday.

Three are also charged with attempted escape.

O'Malley said two of the inmates smashed a window and one tried to climb out. Another was charged with four counts of aggravated menacing. He threatened to stab a responding SWAT officer with shards of glass, O'Malley said.

They caused an estimated $200,000 damage to their housing unit, including breaking security glass, according to a Cuyahoga County spokeswoman.

Officials initially said all 12 teens that lived in the housing pod were involved in the riot. But O'Malley said after reviewing the surveillance video of the riot, they found six of the inmates were not involved in the riot.

The six who are charged face a maximum sentence that would keep them in the Ohio Department of Youth Services until they turn 21. O'Malley said some of those charged could eventually have their cases transferred to adult court because of the seriousness of their past charges.

O'Malley said the riot was planned, and that it appears from the surveillance video of the incident that one inmate gave a signal to begin.

The teens began trashing their jail pod about 7 p.m. Jan. 8, according to a sheriff's department report.

They smashed security glass, damaged cell doors, sprinklers, parts of the ceiling, showers, toilets, light fixtures, a television and windows, officials said.

The Cuyahoga County Sheriff SWAT team was called to help calm the situation.

It took the SWAT team about three hours to get everything under control, according to the sheriff's report.

At least 20 Cleveland police, Ohio State Highway Patrol and sheriff cruisers surrounded the juvenile justice center, which also houses the juvenile court.

An inmate and a SWAT officer suffered minor injuries during the incident. O'Malley declined to provide more information about how both were injured.

Five inmates were initially transferred to the adult Cuyahoga County Jail, but had to be returned to the juvenile jail because state law no longer allows juveniles to be held in adult jails.

The 12 inmates in the pod were all separated in the juvenile detention center after the riot, officials said.

The riot sparked new calls for reform of the Juvenile Detention Center, including O'Malley and County Councilman Michael Gallagher and, both of whom suggested allowing the sheriff to take over operating the juvenile jail. Juvenile court judges operate and manage the juvenile jail, unlike the adult jail, which is run by the sheriff.

O'Malley said on Thursday that any decision on allowing the sheriff to take over operating the juvenile detention center could take longer than a year and that officials had been discussing that possibility prior to the riot.

"There were prior discussions that we had with the judges prior to this incident," O'Malley said. "People were aware there were issues festering at that facility."

In the meantime, he said county officials need to add more guards to the detention center. He said that the county sheriff is already assisting the court and detention center in some day-to-day operations.

"I'm very hopeful that as a result of this troubling situation that improvements will be made," he said.

One inmate charged on Thursday was in the jail on charges that accused him of firing gunshots at a rival group on Nov. 24. Stray bullets struck and killed 12-year-old Abdel Bashiti, who was helping his father out at his nearby beauty supply store on East 116th Street and Buckeye Road.

Five others were being held on aggravated robbery charges, O'Malley said.
