Mariachi bands, folk dancing, carnival rides and record-breaking temperatures greeted thousands of Mexican-Americans who turned out on Saturday to celebrate Cinco de Mayo events in Southern California's predominantly Latino communities.
The largest event was at Olvera Street downtown, where Mexican food and entertainment was to be provided all day Saturday and Sunday. Sunny weather that sent temperatures up to 101 kept daytime crowds at the birthplace of the original Mexican pueblo of Los Angeles relatively small and unusually subdued.
"There were a lot of people downtown, but the heat seemed to mellow them out," said Los Angeles Police Detective Phil Anninos. "When it's this hot, people don't move too fast."
As evening cooled, the crowd swelled to more than 10,000.
Four people were arrested at a Cinco de Mayo protest held in front of an Immigration and Naturalization Service detention center for illegal aliens at 1115 S. Alvarado St., authorities said.
