Multiple agencies responded to the federal detention center in Raymondville after a disturbance was reported inside the prison.
Approximately 30 officers and deputies converged on the grounds of the facility last night.
Action 4 News was told they waited for word from inside the prison as to whether the situation was out of their control.
It wasn't until after 1 a.m. that they were called off.
The detention center officials have not disclosed exactly what went on behind their doors or if anyone was injured.
