The Baton Rouge Fire Department is working to determine what caused a vacant home on North 23rd Street to go up in flames early Sunday morning. Firefighters arrived at the scene on North 23rd Street near Plank Road just before 5 a.m. After entering the home, firefighters discovered the flames coming from a bedroom near the back of the home. The Baton Rouge Fire Department said crews prevented the flames from spreading to nearby homes. However, heat from the fire damaged siding on one neighboring house. The fire was brought under control in about a half hour. The home involved is considered a total loss.
