The 110 Freeway was closed in downtown Los Angeles during Wednesday morning's rush-hour commute due to a shirtless man standing on a freeway sign in an apparent protest against pollution.
The incident was reported around 8:30 a.m. at the southbound 110 Freeway and Beaudry Avenue.
The California Highway Patrol, the Los Angeles Police Department and the Los Angeles Fire Department were all on scene attempting to coax the man to come down.
Video from the scene appeared to show the man holding a bullhorn with anti-pollution banners hanging from the freeway sign. One of the banners read: "Fight pollution not each other."

Around 10 a.m., the man backflipped off the sign and onto one of the inflatable cushions authorities had placed on the ground to soften his landing. He was quickly placed on a stretcher and taken into custody.
Authorites identified the man as 29-year-old Alexander Dunn. Dunn was booked for delaying a peace officer, trespassing and failure to obey a regulatory sign.
The CHP also closed the transition road from the southbound 101 Freeway to the southbound 110 Freeway.
All lanes reopened at 10:30 a.m., according to the CHP.
