RALEIGH - The section of the Wake County jail where a riot erupted Wednesday morning was over capacity with men accused of violent crimes. Authorities said 17 of the 41 inmates were sleeping on the floor.

Wake Sheriff Donnie Harrison said that although crowding can cause tempers to flare, it did not play a role in the fray that left one detention officer hospitalized and at least 11 inmates facing charges of felony rioting and assault on a government official.

"You are going to have this," Harrison said. "In every jail in the state, this is going to happen at some point in time."

The riot remains under investigation but might have been sparked by a dispute over laundry, said Phyllis Stephens, spokeswoman for the Wake Sheriff's Office. "It may have been about laundry not received, that they thought they were getting," Stephens said.

The eighth-floor pod, or cell block, where the incident occurred is part of a maximum security complex that includes five floors of the Wake County Public Safety Center in downtown Raleigh. The facility has four pods on each floor, each pod is designed to hold 24 inmates.

But part of one floor and all of another have been closed for renovations, contributing to overcrowding on the eighth floor. The jail population at the time of the riot was 577 -- 97 over capacity.

The county detention system also includes two minimum-security facilities on Hammond Road that can hold up to 416 inmates each. Both are under capacity but can't be used to ease overcrowding downtown because the sheriff's office doesn't want to mix maximum security suspects with the less violent offenders at Hammond Road.

"We keep them here because some of them have a tendency to not get along with others," Harrison said from the Public Safety Center.

Wake has been aggressive in its long-term planning for jail capacity compared with many local governments, said Stephen Carter, a principal at Carter Goble Lee, a criminal justice consulting firm in Columbia, S.C., that has advised Wake County for years in the planning of its jails.

Because of anticipated growth, Wake is moving ahead with plans for its largest jail so far, to be on Hammond Road. County officials are expected in the next three months to choose an architectural firm to design the jail, which will have at least 720 beds and house processing, medical, food preparation and other services now provided downtown.

Eleven inmates were charged Wednesday morning with felony rioting and assaulting officers at the jail. Two more, including a federal prisoner, were expected to be charged by this morning, Stephens said.

Andrew Deshawn Canty of Clayton was among those charged. Canty is awaiting trial in the death of Paul Berkley, 46, who was shot and stabbed in a North Raleigh park in December 2005, days after he returned to his Clayton home from Iraq.

Three detention officers were injured. One officer, Kenneth Ackerman, was treated at WakeMed Raleigh and released. He suffered an eye injury and cuts to the face, authorities reported. Ackerman has been working at the jail six months, Stephens said. The other officers involved were Michael Hayes, who has been with the sheriff's office for 1 1/2 years, and Lonnie Johnson, an 18-year employee, Stephens said.

The incident began shortly after midnight. Stephens said Ackerman was assaulted by an inmate as he tried to lock down a detention pod for the night. "Others joined in," Stephens said. Hayes and Johnson came to Ackerman's aid.

The 11 charged so far are accused of using their fists to assault the officers. Most of the inmates appeared morose as they stood before a magistrate Wednesday morning.

One of them, Kwesi Nuchrim Holloway, 34, of 3306 Quail Hollow Drive, Raleigh, accused the detention officers of assaulting the inmates as he was led away.

"They be beating us upstairs," Holloway told the magistrate. "They beating us! Beating us!"

Harrison denied the allegation.
