The state prison complex on South Wilmont is shut down because of a huge fight involving hundreds of inmates.
It happened around 9:45 Sunday morning.
Staff was able to quickly stop the fight, but they canceled visitation throughout the prison.
The riot involved 400 inmates, and the Whetstone Unit will remain locked down for the investigation.
Ambulances rushed to the Arizona state prison to take 17 inmates to the hospital and two employees were treated for minor injuries.
Ryanne Costello brought her 6-year-old to see his dad at the state prison.
"He's crying in the car right now because he couldn't go to visitation." She said. "He doesn't understand."
He lives in Phoenix and it has been six weeks since he's since his dad.
"I'm worried more so than anything,' said Costello.
Sandra Martinez drove from Mesa to visit her son here.
"Right now I'm feeling really frustrated because I can't see my son, and I'm not sure what's going on," she said.
She brought his babies to see him.
"We come every weekend," said Martinez.
But they can't see him today.
The Tucson complex is in lockdown, and visitation was cancelled for the rest of the day.
"Anything I hear here in Tucson it scares me half to death because you never know," said Costello.
Both Costello and Martinez will just have to come back next week to see their loved ones.
