San Francisco ? Burning Man became Burnt Man four days early on Tuesday, and a San Francisco performance artist was arrested on suspicion of igniting the signature figure of the counterculture festival in the remote Nevada desert.

The early morning fire scorched about 85 percent of the structure, Burning Man spokeswoman Andie Grace said. Event engineers decided it would be best to dismantle it and rebuild a less elaborate version, accomplishing in two days what normally takes weeks so the figure would be finished in time for Saturday night’s scheduled burning, she said.

The approximately 40-foot-tall wood and neon structure was supposed to go up in flames in the ceremonial climax of the weeklong annual event. Burning Man, an art, music and performance festival that draws thousands of people, began in San Francisco in 1986 and moved to Nevada’s Black Rock Desert in 1990.
