Police are investigating after a man died in a house fire in Melbourne's northeast.
Emergency services were called to Wewak Parade at Heidelberg West about 12.50am on Tuesday to find a single-story unit fully ablaze.
Almost 30 firefighters in breathing apparatus searched the burning building for an unaccounted-for resident and evacuated others in the six-unit complex.
Firefighters used hose lines to stop the flames from spreading to other units.
The blaze was declared under control after about one hour and 15 minutes but a man found inside the property died.
Police established a crime scene and are investigating the cause of the fire.
Arson and explosives squad detectives and an arson chemist attended the units on Tuesday morning.
Officers encouraged anyone with information about the blaze to contact Crime Stoppers.
Ambulance Victoria also treated a firefighter for an injury to his hand.
