A two-alarm fire at a Windsor Mill apartment complex damaged 24 units and displaced 27 residents Tuesday evening, the Baltimore County Fire Department said.

Firefighters arriving on the 7400 block of Brixworth Court around 5:10 p.m. found fire through the roof of one of the two apartment buildings that were involved. Crews battled the fire before bringing it under control and extinguishing hot spots around 7 p.m.

There were no injuries, said Lt. Travis Francis, a fire department spokesman.

The Red Cross said it is assisting 11 households that were displaced, a total of 27 residents.

The cause of the fire is under investigation.
