The police station is Espanola, New Mexico, is set up with state-of-the-art gates and alarms designed to keep out intruders, but the security measures don't seem to be doing a good job of scaring away ghostly trespassers.
On Saturday night, Officer Karl Romero was keeping an eye on surveillance cameras around the station when he spotted something strange in the sally port, or secured entryway.
"At first I thought it was a podilla -- a fly or moth -- then I saw the legs ... and it was a human," he told KOAT TV. "But not a real human. No, a ghost."
The surveillance video of the incident shows a blurry bright, white figure walking across the gated area at night, according to the Albuquerque Journal.
Romero reported the spooky sighting to his superiors. Some, like Detective Solomon Romero, agreed a ghost could be the only possible explanation.
Romero told the station there is no way in or out of the secured area without the gates opening and an alarm sounding.
In addition, other detectives have heard strange noises and seen unexplained images in the lobby of the building, too.
“I do believe in ghosts," Romero told KOAT TV. "I don’t know (what exactly was on the video), but we’ve had some unsolved murders in the area."
However, the police station is not built on an Indian burial ground, he said.
Officers may be willing to believe the strange video shows a ghost, but paranormal investigator Bryan Bonner of the Rocky Mountain Paranormal Research Society isn't impressed.
"That has to be one of the worst videos that I have seen," he told HuffPost by email. "The image appears to have been caused by a small insect (possibly a small spider) crawling on the plastic case that houses the lens."
Bonner said that the fact the police are reporting this alleged ghost sighting may make it seem credible, but says law enforcement officers are given little training in analyzing "ghost" videos.
"Because of that they fall back on the same biases as most people and jump the the conclusion that if they cannot explain it it has to be a ghost, when it is very easy to explain."
