A fire at a home at 4869 Bank Street in Baton Rouge early Monday caused $15,000 in damage and was determined to be arson, fire investigators reported.

Curt Monte of the Baton Rouge Fire Department said firefighters arrived on the scene at 2:01 a.m. to find a bathroom engulfed in flames. No one was at home at the time of the fire, which was quickly extinguished.

In addition to the damage to the bathroom, the rest of the home had light smoke and water damage.
