The detention follows an early-morning frenzy of arson fires across the Hollywood area on Monday. Eleven fires were reported in two hours, beginning at 1:30 a.m., most to cars and carports in apartment complexes, police and fire officials said.
It was unclear early Monday if the fires were connected to a string of arsons in the Hollywood area.
Officials said Sunday that they have linked at least 39 fires to those arsons, which began Friday morning.
