On Wednesday, San Francisco police got a call about 9 a.m. about someone exposing himself outside a US Airways gate, Sgt. Michael Rodriguez said.

An airline employee spotted Marman before he boarded Flight 488, bound for Albuquerque, N.M., and complained that Marman's pants "were below his buttocks but above the knees, and that much of his boxer shorts were exposed," Rodriguez said.

The employee asked Marman to pull up his pants before he boarded the plane, but he refused, Rodriguez said. Marman allegedly repeated his refusal after taking his seat on the plane.

"At that point he was asked to leave the plane," Rodriguez said. "It took 15 to 20 minutes of talking to get him to leave the plane, and he was arrested for trespassing." Marman allegedly resisted officers as he was being led away.
