Andrew Milburn was working at Leeds General Infirmary on Friday night when he decided to send a picture of the hospital's Clarendon Wing just before he started his night shift.
Now it seems Milburn, 21, unexpectedly managed to capture a spooky figure in the shot.
"My girlfriend asked me to prove I was at work so I sent her a picture as I walked to my office,” Milburn told the UK’s Daily Mirror.
"Unbeknownst to me at the time it appears that I captured a ghost figure in the corridors.”
"I have since put this picture on Facebook, it has received thousands of likes and comments and has been shared as far as America."
Milburn added: "It has also been shared on to paranormal investigator groups, many of which believe the picture is real."
So what do his colleagues make of the hospitals unexpected visitor?
"Now people are a bit scared, and apprehensive about going to the loo," Milburn said.
And while many on the interwebs have been accusing the hospital worker of doctoring the image Milburn says he doesn't have a habit of encountering poltergeists.
"I didn't used to believe in ghosts," he told the Mirror. "I was always a skeptic."
