A car fire early Thursday morning on Chiles Avenue was intentionally set, a spokesman for the Lexington Division of Fire and Emergency Service said.
Battalion Chief Joe Best said just before 10 a.m. that investigators have determined that someone set the car on fire.
Anyone with information about the blaze is asked to call the fire department's tip line at (859) 231-5672 or email information to firstname.lastname@example.org, Best said.
Fire crews were sent to the 700 block of Chiles Avenue at 5:40 a.m. Thursday.
A Toyota Avalon parked near a home was on fire, but the building was not damaged, Best said.
Firefighters estimated damage to the car at $5,000.
Meanwhile, investigators were trying to determine the cause of a Wednesday fire at 429 Conley Avenue. That blaze was the third building fire in the same central Lexington area since late December.
The car fire was outside of that zone, which is between Leestown Road and Georgetown Street.
Two of the three building fires were started deliberately, fire officials have said.
A fire that damaged a duplex on Wilson Street early Tuesday was set, firefighters said.
A fire that damaged a house at 519 East Second Street on Dec. 25 was blamed on arson. Authorities charged Charles Goldsberry, 47, in connection with that fire.
Lexington firefighter Jerry Bruner suffered cracked ribs while fighting the East Second Street blaze.
