Staff at a maximum-security prison raised the alarm after seeing a convict trying to escape on CCTV. However it turned out not to be an inmate at all – at least, not of the flesh and blood kind.
In the video footage, the run-down Campo Grande prison in Rio de Janeiro can be seen in the darkness, complete with clothes and bedding hanging out to dry overnight.
A black figure suddenly appears and moves eerily in the night, crawling in front of the locked doors.
The spooky spectre passes through walls, then reappears and floats around the penitentiary. Prisoners believe it’s the spirit of a convict killed at the jail where executions once took place.
The video was uploaded on to YouTube and has garnered more than 300,000 views.
