MARION, Ind. -- Two explosions that led to a large fire at the former RCA manufacturing plant in Marion Saturday evening have been ruled arson.
The fire broke out after 6 p.m. at the complex on Adams Street, which spans several blocks.
Six firefighters were taken to the hospital with minor injuries after being "close to" the explosions, according to Marion Assistant Fire Chief Tony Fox. No further information on their injuries or conditions were available.
Marion Fire Department Investigator Brian Eckstein says both fires set at the explosion areas were intentionally set.
The fires caused more than $250,000 in damages to the building.
No arrests have been made at this time, but Eckstein says investigators are looking into leads.
Anyone with information about the fire should call 765-668-4474.
