Officers responded and took the man into custody. "After the interview (with the arson suspect) and additional investigative steps, looking at some additional evidence that was present, they made the determination that there was not enough probable cause to arrest this person on arson or suspicion of arson, and therefore this person was arrested on felony probation violation," Choi said.

He said the investigation is ongoing. "I would like to thank those community members that were involved in this and helping us, bring this person to our attention so we can have a thorough investigation."
