SAN BERNARDINO, Calif. - A 16-year-old boy arrested for investigation of arson is under investigation in connection with more than a dozen Southern California wildfires, authorities said Thursday.

The fires had a "commonality," but investigators were not releasing any details of how they might be connected, San Bernardino County sheriff's spokeswoman Jodi Miller said.

None of the fires involved in the investigation led to serious injuries or death, and property damage was minimal, said Doug McKain, a unit chief with the California Department of Forestry and Fire Protection.

The youth, whose name was withheld because of his age, was arrested Wednesday near a fire that erupted near the city Yucaipa and was booked into Juvenile Hall.

The district attorney's office was awaiting reports, and no charges had been filed, said spokeswoman Susan Mickey. She said it had not been determined whether the teen would enter the juvenile or adult court systems.

The Sheriff's Department said deputies responding to a report of arson were told by witnesses that a youth had left the Yucaipa fire location on a bicycle. The deputies searched the area and found a youth.

Sheriff's spokeswoman Arden Wiltshire said the youth was cooperating with investigators.

"Through perseverance, swift response and determination this arson siege has been brought to an end," McKain said.

Fire spokesman Bill Peters said the 347-acre Yucaipa fire was 60 percent contained.
