The Baton Rouge Fire Department fought two early morning blazes Sunday, one displacing a family and the other being investigated as arson, a release says.

A window air conditioner sparked the fire that sent a family of four from their home at 4756 Enterprise St., Fire Department spokesman Barry Mounce said in the release.

Everyone escaped unharmed, the release says.

The fire started about 12:45 a.m. in a bedroom and spread to a hall before firefighters put it out, Mounce’s release says.

Flames gutted the bedroom and heavy smoke damaged the rest of the house, the release says.

The Red Cross was at the scene to help the family, the release says. The Fire Department estimated damage at $50,000.

The other fire started about 12:10 a.m.. in a vacant house at 3728 Sycamore St., Mounce said in another release.

It started in the small, one-bedroom house and caused extensive damage before it was controlled, the release says.

The suspected arson caused an estimated $20,000 in damage, the release says, and is under investigation.
