Jamestown firefighters responded to a fire at the Arcade Building on North Main Street Wednesday afternoon. No injuries were reported. Jamestown Fire Department Chief Andrew Finson said initial responding crews found heavy fire inside the structure. Multiple hoses were used to get to the "seed" of the fire to knock it down, Finson said. He added fire department crews are often called to the structure for various reasons, as the old building is in "rough shape." Wednesday, crews inspected the building to make sure it was still safe for everybody walking by. The cause of the fire Wednesday is still under investigation. Finson said at the scene of the fire a criminal act had not been ruled out.
