PASADENA — Police and fire investigators arrested a Pasadena man Friday on suspicion of lighting an arson fire that caused $200,000 to a carport and the vehicles parked inside last weekend.

Artist Knox, 29, was arrested about 5:30 p.m. in connection with the arson fire, which erupted about 2 a.m. Sept. 8 in the 600 block of South Marengo Avenue, Pasadena police Lt. Diego Torres said. He was being held in lieu of $250,000 bail at the Pasadena Police Department’s jail.

The arrest came after a week of investigation by Pasadena Fire Department arson investigators, fire spokeswoman Lisa Derderian said.

Information regarding a motive for the arson or the circumstances of the arrest was not released Saturday due to the ongoing investigation, she said.

A passerby first reported the fire, which ultimately scorched a carport, destroyed two vehicles, badly damaged three others and caused minor damage to a neighboring business, officials said.

After firefighters extinguished the flames, investigators quickly determined the fire had been intentionally set.
