VISTA -- A fire that caused $100,000 in damage to a Vista church was deliberately set and a $5,000 reward is being offered for information leading to arrests, a U.S. Bureau of Tobacco, Firearms and Explosives spokesman said Wednesday.

The federal agency is assisting the Vista Fire Department in the investigation of the Oct. 24 arson fire at the West Coast Baptist Church, ATF spokesman Michael Hoffman said. He said investigators found evidence that the fire was not accidental, but he declined to say what they found.

A passerby reported the fire at the church at 1525 Buena Vista Drive about 7:15 a.m. on Oct. 24. Hoffman said investigators had no concrete leads about motives or suspects.

Anyone with information is asked to call (888) ATF-FIRE.
