Police are investigating a pair of early morning fires in northeast Sioux Falls that officers say may be suspicious.
Police and Fire Rescue responded to the first fire in the 1300 block of East 3rd Street just after two o'clock Saturday morning.
Firefighters quickly put out the fire burning in a pile of wooden doors in the yard.
While responding to the scene, they spotted a second fire burning in some trash in the 700 block of North Sherman, just a couple of blocks away.
No one was hurt in either fire.
Police have not made any arrests.
