A 16-year-old Southern California boy has been charged as an adult for allegedly starting two arson wildfires in San Bernardino County earlier this year.

District attorney spokeswoman Susan Mickey said Wednesday that Ricky Sean Lukacs will be arraigned in adult court on Dec. 28.

He is charged with two counts of arson of an inhabited structure and is being held in juvenile hall.

Authorities say the teen set two fires in the Yucaipa area over a two-day period in late August. The fires did not cause serious injury or death.

Yucaipa is 65 miles east of Los Angeles.
