NORTH HOLLYWOOD — Authorities Thursday were investigating whether four tree fires in the North Hollywood area were intentionally set.

Los Angeles Fire Department spokeswoman Amy Bastman said there were four fires reported on Thursday morning considered “suspicious” because of their close proximity — and all are under active investigation.

The first fire was reported at 5:35 a.m. on the 5900 block of Carpenter Avenue; a second blaze was called in at 5:46 a.m. at the 5900 block of Irvine Avenue; the third fire was reported at 5:50 a.m. on the 11600 block of Oxnard Street; and the final fire was at 5:53 a.m. on the 5700 block of Beck Avenue.

Bastman said she had no further information, and anyone with information about the fires should call their local authorities.

Officer Irma Mota of the Los Angeles Police Department’s Media Relations Division said a suspect is wanted in connection with the first fire. He is described as a man on a bicycle wearing dark clothing. Mota had no further information.

Thursday’s fires follow a series of blazes in the early morning hours of Sept. 25 that fire officials also believe were intentionally set. One of those fires was reported in the 6100 block of Carpenter Avenue — just a couple blocks up the same street where the tree fired occurred Thursday.

The September fires damaged a vehicle and a window of a house, but no one was hurt. No suspect description was released in the earlier case.
