A man has been arrested on suspicion of arson after a fire broke out at a mental hospital.
The 43-year-old was held as firefighters tackled the "severe" blaze at the George Bryan Medical Centre in Tamworth on Monday night.
Images showed flames and smoke billowing from the building's roof, part of which appeared to have fallen in.
Ten fire engines attended the scene, and Staffordshire Police said a suspect, from Tamworth, had been detained.
A spokesman from Staffordshire Fire and Rescue Service (SFRS) earlier said there had been reports of one of the patients absconding during the commotion caused by the blaze.
A police spokesman told the BBC the patient had been found soon afterwards.
A spokesman from SFRS said that there was "quite a lot of the building involved" in the blaze.
"We're trying to sacrifice part of the building and let that burn to prevent it from spreading to the rest of the hospital," he added
