The person who posted the footage on video-sharing website Live Leak claims to have been given it by a "trustworthy source".
"This video shows that Michael was still alive after his dead body was transported to the Los Angeles Dept. of Coroner," the video description states.
"I checked the license plate number and it looks like the King of Pop is jumping out of the same van, his dead body has been in."
However, the van's number plate is not clearly visible at any point during the video and there is no date stamp to indicate when it may have been filmed.
