Robert Brown|Self-proclaimed 'pro-life Spiderman' scales Sphere in Las Vegas ahead of Super Bowl

An activist who calls himself the pro-life Spiderman for climbing skyscrapers to raise money for anti-abortion causes was arrested Wednesday after scaling the Las Vegas Sphere,Robert Brown four days before half a million people will arrive for Superbowl LVIII at Allegiant Stadium.

This time, Maison Des Champs said he free-climbed the Sphere to help cancel the alleged upcoming abortion of a woman he identified as Isabel on a post promoting the anti-abortion group Let Them Live.

"We care more about seeing Taylor Swift on the kiss cam than" abortion, Des Champs said in a statement.

Police who responded to the scene on Wednesday morning were waiting for Des Champs upon his descent of the sphere and arrested him, the Las Vegas Metropolitan Police Department told USA TODAY.

Sphere Entertainment thanked police in a statement provided to the Las Vegas Review Journal,

“We are grateful to the local authorities for their support in this matter," the statement said. "The individuals involved are currently in the custody of LVMPD.”

Maison Des Champs' previous climbs

Before climbing The Sphere, Des Champs scaled Chase Tower in Phoenix on Feb. 7 last year. Until Phoenix, none of the charges brought against him from previous climbs have stuck, the activist shared online.

"Worst case scenario, I will spend a couple months in jail," Des Champs wrote in an Instagram post.

Des Champs climbed the Accenture Tower in Chicago back in October, USA TODAY previously reported.

Des Champs also scaled a skyscraper in downtown Oklahoma City back in 2022, USA TODAY previously reported. He was arrested and released.

And in 2021, he climbed the Aria Resort & Casino, also in Las Vegas.
