Investigations are underway after two overnight fires in Winnipeg.

The Winnipeg Winnipeg Fire Paramedic Service (WFPS) was first called just after 2 a.m. to a fire in a commercial building in the 1500 block of Regent Avenue West.

Heavy smoke was pouring from the building when firefighters arrived. Crews launched an offensive attack, declaring the fire under control at 3:07 a.m.

Crews searched the building and no occupants were located. No injuries were reported.

The cause of the fire is under investigation and no damage estimates are available.

Just 10 minutes after the first fire was extinguished, the WFPS was called to another fire.

At 3:17 a.m., the WFPS responded to reports of a fire in a one-storey home in the 400 block of Dumoulin Street. When crews arrived on scene, smoke was coming from the home. Crews launched an offensive attack, declaring the fire under control at 4:21 a.m.

All occupants safely self-evacuated before crews arrived. Paramedics assessed two patients on scene but no transportation to hospital was required.

The cause of the fire is under investigation and no damage estimates are available.
