Watch the incredible moment these inmates broke out of their cells to save a prison guard's life
Most people would expect prisoners breaking out of their cells to take flight.
But for a group of inmates held at a prison in the US, their reasons for escape were more altruistic.
Prisoners at Parker County Jail in Texas recently broke out of their holding cells in an attempt to save a guard who slumped over after losing consciousness.
CCTV footage broadcast by local news station WCAA-TV shows eight inmates leaving their cells and banging on the walls, in hope they can alert other guards for help.
On hearing the commotion, the prison officers arrived and called the paramedics before locking the inmates back in their cells.
"They thought it was a fight," inmate Floyd Smith told WCAA-TV. "They thought we were taking over."
"It never crossed my mind not to help, whether he's got a gun or a badge," inmate Nick Kelton added. "If he falls down, I'm gonna help him."
Officials declined to identify the guard, who works for a private contractor, but he's expected to return to work next week and is believed to be recovering from a heart attack.
The doors have now been reinforced at the prison to ensure that inmates can't escape again - no matter how honest their reason.
