A fire Thursday at a vacant house on Kentucky Street was deemed by fire officials to be an arson, and the blaze was so intense, it burned the home to the ground and damaged a second vacant building next door.

The Baton Rouge Fire Department responded to the fire at 1840 Kentucky Street at 4 a.m. and had the flames under control in about 10 minutes, according to Curt Monte, a spokesman for the department.

Monte said the house, which had an estimated value of about $20,000, was destroyed. Damage to the second building, which was not occupied, was estimated at about $1,000.
