A second person has been charged over an alleged deliberately lit fire at a commercial business in Port Kennedy.
The 32-year-old man is accused of lighting a fire at the premises, located on the corner of Paxton Way and Fielden Way, around 9.40pm on June 14.
Seven vehicles were destroyed in the blaze leaving a damage bill of $200,000.
Last month, a 32-year-old Warnbro woman was charged over the fire.
Police have since confirmed a second person, a man from Baldivis, has also been charged with criminal damage by fire.
He is due to front the Rockingham Magistrates Court on September 10.
The investigation is continuing and officers urge anyone with any information relating to this matter, to contact Crime Stoppers on 1800 333 000 or via www.crimestopperswa.com.au
Rewards of up to $25,000 are available for information that leads to the identification and conviction of an arsonist.
