On the 23rd floor of an old New York City skyscraper, a man wearing a suit was seen running between exterior ledges.
Video of the mystery daredevil standing on a corner section the roof during the rain outside.
He looked like he was taking pictures with his cellphone.
The man then ran down the penthouse roof and jumped onto many more before opening a window to climb inside.
The spectacle was staged at an impressive residential building, built in 1905, near Wall Street.
The video was shot by Erik Ljung, an Emmy-nominated cinematographer. While on a shoot, he noticed the man from the street.
“He didn’t look distressed at all. He looked real comfortable up there,” Ljung said. “He was making a call, he was taking pictures. Then he got right back to the window he popped out of.”
According to one report the man was a contractor looking for a leaky skylight.
