Melbourne North Crime Investigation Unit detectives are continuing to investigate a suspicious fire at a restaurant in Carlton last year, Victoria Police say.
Emergency services were called to the Lygon Street restaurant near Beard Place about 12.50am on 2 October.
Neighbouring homes were forced to evacuate, with the building extensively damaged.
Investigators have received reports of a man wearing a breathing mask, dark clothing and white gloves, who was running from Beard Place around the time of the fire.
Police have released a facial composite and an image of a man they believe may be able to assist with their enquiries.
Investigators are also appealing for an anonymous caller who contacted Crime Stoppers.
Anyone with information is urged to call Crime Stoppers on 1800 333 000 or submit a confidential crime report at www.crimestoppersvic.com.au
