A chilling piece of security camera footage appears to show a ghost terrorizing a school at three in the morning, opening lockers and ripping down signs in the dead of night.

Security cameras at Deerpark Christian Brothers School in Cork City, Ireland captured what appears to be a VERY angry ghost causing a ruckus in the hallways in the middle of the night. The school’s deputy principal Aaron Wolfe, who is a “self-proclaimed skeptic,” acknowledges that the school is one scary looking building. Despite the video, Aaron himself is not totally convinced that the school is actually haunted.

“We couldn’t understand how this had occurred,” Aaron said. “If it is a prank, it’s very well done!”

Aaron went on to explain that Deerpark CBS is located on a piece of land that is “rich with history.” In the midst of the Irish famine, the site the school currently sits on was the location of the gallows, meaning it was where people were hung. While Aaron does not understand how what’s happening in this video could have taken place, he has a message for anyone who thinks school officials are behind it.

“People have suggested that we’ve used a green screen or edited someone out,” he said. “I wish our school had these types of resources,”
