The man behind a series of online videos showing him creeping around after hours inside buildings in Ottawa says he will now stop.

In a video posted on YouTube Thursday, Jay Station said the media attention surrounding his antics has garnered the attention of police.

"I'm making this video to tell you guys that I can no longer do these 24-hour challenges because, basically, I'm risking my freedom to do that and that's something I'm not prepared to give up," he said.

The "24-hour overnight challenge" is part of a global trend that involves people hiding inside businesses until they close, and filming their exit without sounding the alarm or running into security guards.

On his YouTube channel, Station posted footage of himself walking around the Rideau Centre, TD Place Stadium and a bowling alley on Merivale Road after closing time.

"I want to make it clear right now … that when I was doing these 24-hour challenges I did not damage any property. I never broke into any one of these places. And I never stole anything. I would never steal, ever," he said.

Station also warned others not to try to perform the challenge, highlighting the consequences that could result if caught.

"That is the worst decision you could ever make. Do not try these overnight challenges, guys. They are illegal and they can get you in a lot of trouble."

Ottawa police said they became aware of Station's videos last week and are investigating. They also said they consider his pranks breaking and entering.
