Arson investigators took a person into custody after a string of small fires that appeared to be intentionally set in North Long Beach on Tuesday, according to authorities.

Firefighters doused three of the fires around 10:30 a.m. after they found them burning near the intersection of Atlantic Avenue and Del Amo Boulevard, Long Beach Fire Department Capt. Pete Kusel said.

All three of the fires were burning a short distance from each other, according to Kusel. One was burning a mattress, the second was in some brush and the third was consuming a small tree, he said.

About four hours later, a fourth fire burned through a palm tree and some electrical wires in the same area, according to the fire department.

The fourth blaze briefly caused a power outage to a few homes, but, otherwise, no significant damage was reported, according to Kusel.

Kusel said authorities took the male suspect into custody related to the fires, but investigators are still looking for more information. He asked that any witnesses call (562) 570-2537.
