Orlando police confirmed a break-in at Pulse nightclub Wednesday night, just one month and a day after a gunman entered the club with an assault rifle and opened fire, killing 49 and injuring dozens more during an hours-long standoff with police.

The club has been an active crime scene since the massacre, and was released back to owners Barbara and Rosario Poma Wednesday morning.

According to Orlando police, Pulse employees in the area had noticed the club's vehicle gate was open around 3am but didn't realize until later that morning that the front door, which had been secured with plywood, was also open.

Though the club is equipped with security systems and cameras, they were not activated on Wednesday night. It's unclear what the vandals were doing or attempting to do there.

"Since June 12, we have seen the worst and best of human behavior," Barbara Poma said in a statement.

"We are disappointed that someone felt compelled to violate the privacy of our beloved Pulse Night Club and the sacred place it has now become. We have faith in the Orlando Police Department and its investigation of this break-in. The club will continue to remain closed to the public as we work to plan the future of Pulse."

Speaking to WFTV, Barbara Poma's husband, Rosario, called the break-in "unspeakable."

"They pried the wood off the doors that was screwed to the walls," he said. "What did they do inside in there? … We don't know. I'm securing all the doors so it can't happen again."

"It’s a little emotional right now. I have no idea why somebody would come to a place where such a tragedy took place."
