INDIANAPOLIS – Firefighters say more than three dozen cars caught fire Wednesday morning at a south side business.

Crews used tanker trucks to bring water deep into the auto yard. Once the water supply was established, crews had the fire under control in about 40 minutes.

Indianapolis Fire Department crews were dispatched around 1:45 a.m. to Insurance Auto Auctions located at 3202 S. Harding St. IFD found about 40 cars on fire when crews arrived at the location.

Heavy fire destroyed the cars, IFD said.

No injuries were reported. The fire remains under investigation. IFD said the company was looking into the possibility that a lightning strike from thunderstorms overnight may have started the fire.
