He made it to the top of the building without a harness or safety gear of any kind. That's where he was met by authorities and taken into custody.
He was reportedly posting on Instagram as he climbed. He's been identified as Maison Des Champs, a rock climber who calls himself the Pro-Life Spiderman.

On his website, he says he recently started climbing sky scrapers to end abortion. He posted video during the climb against a particular OB/GYN in Washington D.C.
This climb was in response to the leaked draft Supreme Court opinion that would throw out the landmark Roe v. Wade abortion rights ruling that has stood for a half century.

Police say that around 9:21 a.m. PST, officers were flagged down about the man climbing the building. Officers observed him on the side of the building several floors up, wearing climbing gear.
Officers attempted to make contact with the climber as he ascended to safely remove him from the building, but instead surrounded him right as he arrived at the top.
