One man was airlifted to Hennepin County Medical Center in Minneapolis with serious smoke-inhalation injuries after an overnight apartment fire in Albert Lea.

Firefighters, Albert Lea police and Freeborn County sheriff’s deputies responded to the fire, at the Landmark Apartments at 517 E. 4th St., around 3 a.m. today. Firefighters broke down the door of an apartment on the second floor to find the 37-year-old man unconscious in the smoke-filled room, the fire department said.

He was taken to Naeve Hospital in Albert Lea before being taken to Minneapolis. The man’s name was not immediately released.

Firefighters extinguished the fire shortly, and most of the damage was caused by the smoke, the department said. Two Albert Lea police officers suffered from smoke inhalation; one was treated at the scene and another was treated and released at Naeve Hospital.

Other residents of the three-story apartment building were displaced.

The fire department and state fire marshal are still investigating the cause of the fire.
