LOS ANGELES (AP) - Authorities arrested a man Monday in connection with dozens of suspected arson fires that destroyed parked cars, scorched buildings and rattled much of the nation's second-largest city over the New Year's weekend. The suspect resembled a "person of interest" captured on surveillance video near a carport. The man, believed to be 20 to 30 years old, had a receding hairline and a shoulder-length ponytail and was seen emerging from an underground parking garage on Hollywood Boulevard where a car fire was reported. Police declined to identify the suspect, but said he was to be booked later on arson charges arising from more than 50 blazes that have flared since Friday in Hollywood, neighboring West Hollywood and the San Fernando Valley. The blazes caused an estimated $2 million in damage and forced many apartment dwellers from their homes. But there were no serious civilian injuries. One of Saturday's fires occurred at the Hollywood and Highland entertainment complex, a popular tourist destination bordered by the Walk of Fame in a neighborhood that includes Grauman's Chinese Theatre. Damaged buildings included a former home of Doors singer Jim Morrison in Laurel Canyon. Most of the fires began in cars. Authorities have not said how they were started. Investigators declined to provide any other immediate details, saying they did not want to jeopardize the case. A news conference was scheduled for Monday evening. Hundreds of investigators, police officers and firefighters raced to deal with the blazes. Police conducted extra patrols all weekend, and the noise of helicopters and sirens persisted virtually nonstop in Hollywood. Investigators were still busy Monday mapping out the sequence of the blazes, examining more than 100 clues and interviewing witnesses. The fires left behind a trail of smoldering debris. Some other deliberately set fires were reported Thursday in Hollywood, and two people were arrested. But police said Monday that those suspects were not connected with the 53 other blazes.
