Police are investigating a series of suspicious fires along Ventura Blvd. on Wednesday night.
Fire crews responded to at least six fires over a period of about an hour, from Studio City to Sherman Oaks.
Most of the fires started in trash bins including one behind a strip mall in the 13900 block of Ventura Blvd. that spread to neighboring two-story apartment building, according to LAFD spokeswoman Katherine Main.
Police are looking for a heavy-set Hispanic man, about 6 feet tall, wearing a tank-top and riding a BMX bike.
All of the fires appear to be arson, fire officials said.
No injuries were reported.
