Samantha Hartsoe was investigating the source of a cold draft in her New York home and tracked the air to her mirror in the bathroom.

When she removed the mirror, Hartsoe found it was hiding a large, square hole into a dark room - which turned out to be a vacant apartment.

She told NBC: "Curiosity killed the cat, curiosity is going to kill me.

"I can't not know what's on the other side of my bathroom."

Hartsoe explored the entire residence where she found an uninstalled toilet and an empty water bottle. She made sure that the door to the apartment was locked before making her way back to her own property.

She added: "I was kind of expecting there to be somebody, especially with the water bottle being there."
