Police are investigating a suspicious fire at Canberra's largest mosque overnight.
Police said ACT Fire & Rescue responded to an alarm at the Canberra Islamic Centre on Clive Steele Avenue in Monash about 11.30pm Saturday.
"On arrival, fire fighters located smoke coming from the prayer hall at the centre, and were quickly able to extinguish a small fire within an adjacent store room," police said in a statement.
The expanded Ahmad Al Sabah Masjid and Islamic Education Centre opened in May last year. It serves as a focal point for all Muslims in Canberra, providing a place for prayers, education, cultural events and religious gatherings.
The Monash centre has been the target of sporadic attacks. In 2014, vandals broke in twice over a two-week period and caused extensive damage.
Police ask anyone with information about this incident, or anyone who has dash-cam footage or CCTV that captured vehicles and people in the area around the time of the incident, to contact Crime Stoppers on 1800 333 000, or via the Crime Stoppers ACT website and quote reference 6436578.
