Sixteen units were affected after the Austin Fire Department extinguished a blaze at a two-story apartment building in North Austin Monday evening.

Austin Fire said they received an alert call for a second alarm fire in the 8900 block of North Interstate 35 between Rundberg Lane and U.S. 183 at 5:08 p.m.

When crews arrived, flames were coming out of at least one unit. Crews attacked the blaze that began on the second floor with multiple lines. At 5:50 p.m., AFD said they had reduced to first alarm units with most of the visible fire put out, and did not find anything or anyone in their search of the building.

At around 6:30 p.m., an official with AFD said that 16 units have been "heavily affected" by either smoke, fire or water. According to AFD, 10 people are displaced.

The cause of the fire remains under investigation.
