MISSOULA, Mont. -

Missoula fire crews are mopping up an early morning garage fire.

The call came in at about 5:30 Thursday morning.  Officials say flames were shooting out of the roof but they were able to knock down the flames pretty quick.

The out-building is located in the alley between North 2nd Street West and North 3rd Street West in Missoula. 

Northwestern Energy also responded because of the close proximity to power poles.

The cause is unknown at this time but investigation is underway.
