PHILADELPHIA (AP) - A guy who goes by the name Carson King has posted an online video of himself climbing Philadelphia City Hall and its tower, which reaches about 500 feet into the air.

King tells KYW-TV (http://cbsloc.al/2vjqkwt ) that he climbed the building while scaffolding was up earlier this year due to renovations and the maintenance of the bronze William Penn statue at its apex.King say the nearly seven-minute video isn't meant to spawn copycats saying, "I strongly suggest a normal citizen doesn't try this."King says he climbed the building to take pictures from a unique vantage point, nothing more.City spokesman Mike Dunn says officials have seen the video and called the actions "dangerous and illegal."It's not clear whether the city will try to prosecute the climber.
