Ben Schneider, 28, posted a clip on his YouTube channel of him walking on a tightrope across the two towers earlier this month.

The abandoned towers have become a popular spot for artists to create content and paint graffiti.
Schneider talked with Eyewitness News about why he decided to do the stunt despite knowing he was breaking the law.
"The police are definitely after me, which is why it's very risky for me to be doing this interview," he said. "There's a police officer right there. If that police officer just turns his head and looks at me, I'm in jail... With great risk, comes great reward.
"It was very scary. I was looking down... When you get scared you start to shake and when you shake, the line shakes and then you fall off," Schneider added. "I didn't want to fall. You just have to calm your mind."
He said he wants to inspire people to live their best lives.

Police were guarding the towers, but Schneider said a group of friends held up religious signs as a decoy so that he could enter.
Police are investigating.
