An inmate at a hospital tried to escape Texas authorities over the weekend by climbing through the ceiling.

The attempted escape happened Sunday when an inmate accused of aggravated robbery was being guarded by a Dallas County sheriff's deputy during treatment at a Dallas hospital, CBS News reports. The inmate, who was in leg restraints, had asked a deputy to escort him to the bathroom.

While in the restroom, the inmate allegedly climbed into the ceiling and tried to escape. Once the bathroom break jailbreak was discovered, the hospital was put on alert, and Dallas police, as well as a DeSoto police K-9 unit, were called in to help.

A hospital building engineer told deputies that the ceiling that the inmate had climbed into was restricted to a limited area. That gave authorities a specific space to look for the suspect.

After hearing the K-9 unit during the search, the inmate surrendered and was taken into custody. No injuries were reported.

The incident is under investigation, and the inmate is expected to face additional charges stemming from the escape attempt.
