POLICE have confirmed they are investigating a series of suspicious or deliberately lit fires in Perth’s southern suburbs but are not sure whether a serial arsonist or group is responsible.

Figures supplied to the Herald show that since February arsonists set fire to cars and property in South Fremantle, Hilton, Hamilton Hill, Spearwood and Munster.

Police say incidents may be missing because details have not yet been entered into the computer system.

Incidents are included where cause is determined to be deliberate or suspicious.

In Yangebup, a 58-year-old man was charged this week with cultivating cannabis after firefighters allegedly found 30 plants in his burning shed on Shallcross Street in Munster.
