Do you believe in ghosts?
One police officer certainly does - and he even has the video footage to back up his claims.
Officer Karl Romero based in New Mexico, was stationed in the surveillance room monitoring the CCTV cameras when he noticed some spooky goings-on in the gated area.
He claimed he spotted a phantom-like creature gliding across the sally port (a controlled entryway which is completely sealed off).

Detectives say there is no way in or out of the secured area without the gates opening and an alarm sounding, KOAT Action News reported.
"I do believe in ghosts," Romero told the station.
"I don't know (what it was on the video), but we've had some unsolved murders in the area."
His fellow police officers backed up his claims, revealing that they've been hearing strange noises at night and seeing unexplained images in the lobby area for a while now.
