A tip to deputies at the Pueblo County Jail has uncovered a plan by inmates to bring a gun or drugs into the facility.
Deputies shut down the fourth floor maximum-security wing of the jail.
They discovered the outside of a window had been moved about 4-inches.
Officers think the plan may have been to lower strings or ropes to the ground. Where accomplices would attach contra-band.
Investigators also believe detention officers were going to be attacked after the weapons got in.
