Firefighters were called on twice to extinguish a fire at the same residence on Sunday.
The home in the 200 block of Pritchard Avenue, reported to be abandoned, became engulfed in flames at around 2 p.m.
However, firefighters returned just before 8 p.m. to put out a second fire.
Damage is estimated at $180,000.
The cause of the fires remain under investigation.
UPDATE: Winnipeg police arrested three teen boys, between the ages of 13-14, in the area of Charles Street and Pritchard Avenue Sunday evening. Police say the teens broke into the house and deliberately set the fire. All three were taken into custody.
