Mystery of 'Creepy' Light Spotted in Window of Abandoned New Orleans Hospital Solved

The hospital in New Orleans went defunct after Hurricane Katrina.

— -- Photos of a mysterious light spotted inside the window of a dark, abandoned New Orleans hospital have gone viral on Facebook after catching the attention of employees at Tulane Medical Center across the street.

Tulane anesthesiology technician Michael Arbon told ABC News that he took photos of the light around 5:30 a.m. today after seeing other employees' photos circulating on Facebook.

"It was pretty neat but also a little creepy," Arbon said. "To me, and to the other lady who posted photos on Facebook, it looked like a nice, little Christmas tree in the dark, abandoned building."

LSU police went inside the vacant building and removed what turned out to be 2-by-4-foot wooden boards wrapped with lights, according to LSU director of information services Leslie Capo.

Capo said police were treating the incident as a break-in.
