A ghost caught by a CCTV in Australia

On April 13, 2018, NSW Police Force, in Australia, has published weird video on their Facebook account. On these images, we can see the ghost of a janitor

This video has taken at police station car park.

New South Wales Police Force claims:

Wanting to know who'd left a garage in a police station car park open yesterday, police reviewed the CCTV - what it showed sent shivers down our spines....

Just before dawn, with the car park empty and quiet, a garage, that hadn't been used in days, suddenly starts to open of its own accord. With the door half open, a broom flies out, as if propelled by a 'spirited' janitor. It stays upright, then falls to the ground and gives one final kick, looking like it's in the final throes of possession.

A technician is currently inspecting the door. The 'possessed' broom sounds like a job for the Ghostdusters!

*Note: even though it's Friday the 13th, this is actual CCTV footage.*
