SAN FRANCISCO -- Hoping to head off another night of looting and violence, Mayor Frank Jordan extended the city's curfew for a second night as several groups vowed to defy the order.
San Francisco remained under a state of emergency Friday, believed to be the first time the city has taken such a step since the rampant looting following the massive 1906 earthquake.
Jordan said he extended the curfew, which will be in effect from 9 p. m. to 6 a.m., after learning that various groups had vowed to demonstrate again Friday night to protest the acquittal of four white Los Angeles police officers accused of beating black motorist Rodney King last year. The mayor said peaceful demonstrations would most likely be allowed, but that police would arrest vandals and looters.
'Any kind of property damage or physical violence will not be tolerated,' Jordan said. 'We do not want to let the situation get out of control.'
The mayor said the city would impose an 'arrest and detain' policy in an effort to keep troublemakers off the streets. Police in the city and county arrested more than 1,100 people Thursday as multiracial gangs roved through San Francisco smashing dozens of windows, lighting trashcans on fire, looting stores and taunting peace officers. At least 250 felony charges have been filed as a result of the violence.
Piles of shattered glass, scorched trashcans and rubble covered by plywood greeted people who returned to work Friday morning, and scores of looted stores remained closed so owners could clean up and assess the damage.
While the mayor had no damage estimates, he said the city has already spent more than $260,000 on police overtime and sanitation crews to clean up broken glass and rubble.
Looters in the posh Union Square district broke windows at some of San Francisco's prestigious stores, including Macy's, Victoria's Secret and F.A.O. Schwarz. There were no immediate estimates of damage.
Phil Horowitz, manager of Layne's Jewelers on Market Street was trapped in his store with other employees Tuesday night when more than 40 looters broke the store's front window and made off with all of the jewelery in the display.
'We were worried that we were going to get killed,' Horowitz said. 'All the precious jewelery was taken from the store.'
Horowitz said he saw little connection between the looting and the Rodney King verdict.
'We are of the opinion that this whole thing is just an excuse for looting,' he said. 'They came from home with pipes in hand, and now their mothers will have precious jewelery for Mother's Day courtesy of us.'
Jordan also said the looters were taking advantage of a tense situation for personal gain.
'Not all of (the protests) had to do with the Rodney King incident,' he said.
San Francisco joined Los Angeles in declaring a state of emergency in the wake of Wednesday's King verdicts.
Riots in Los Angeles killed at least 37 people, injured more than 1, 400 and left hundreds of businesses in ashes. King went on television Friday afternoon to plea for an end to the violence in an emotional appearance.
Police from surrounding counties remained in San Francisco to help quell violence. At least one organization, known as Roots Against War, vowed to defy the curfew and demonstrate Friday night.
At the same time Jordan announced the curfew, protesters gathered in various parts of the county. One group converged at the parking lot of the Stonestown Mall near San Francisco State, where many students shut down Interstate 280 on Thursday. A peaceful group of high school students also organized a march across the Golden Gate Bridge.
In response to the curfew order, the San Francisco Giants also canceled Friday night's baseball game at Candlestick Park against the Philadelphia Phillies.
The mayor also reported five police officers had been injured and five buses had been vandalized. One alleged looter was shot in the leg by police after reportedly swinging a baseball bat at the officers.
The city's subway and bus systems returned to regular schedules Friday.
