A May Day rally in Santa Cruz erupted into chaos Saturday night when about 200 protesters, some with torches, stormed the city's main street. Some smashed windows and spray-painted anarchist graffiti, police said.

Jimi Haynes, 24, was arrested on suspicion of felony vandalism after witnesses saw him shatter two windows at a Pacific Avenue jewelry store, police said. They said Haynes, a parolee from Fresno County, had been in Santa Cruz for several weeks and had learned of the rally by picking up a flyer at a "local anarchist cafe."
