Footage showing someone riding atop a lift within a Preston tower block has been condemned by Lancashire Fire and Rescue Service.
The clip is taken inside the Crystal House lift shaft.
Posted onto YouTube by RYEGI the clip shows the lift being operated and the person going up and down the lift.
A message with the video says: “Please do not attempt to copy anything you see in this video without the full knowledge of how to be safe.”
But a spokesman for the fire service said it should never be attempted.

He said: “Reckless, dangerous and irresponsible behaviour such as this can result in injury and death. Exposure to moving machinery and live electrical circuits are the most obvious hazards. Even though the perpetrators who posted the video dodged those hazards on that occasion there is no assurance they would do so again.”
“They have wilfully disregarded the possible impact of their actions on others, not least legitimate users of the lift who may become trapped in it when it malfunctions as a result or those who have seen the video and are inclined to ‘copycat’ what they’ve done.
“Inevitably, were the worst to happen it would be firefighters who would be called in to the rescue of ‘lift surfers’ or victims of their illegal activity.”
