The fire caused about $30,000 in damages.

A fire that caused about $30,000 in damage to a Dover house trailer was the result of arson.

Assistant State Fire Marshal Michael G. Chionchio said the blaze was reported at about 11:16 a.m. Thursday, Dec. 6 in the first block of East Pinewood Drive, near South State Street.

The Dover Fire Department took charge of fighting the fire, he said.

An investigation afterward showed the blaze was started deliberately and fire marshals have found significant leads in the investigation to determine responsibility for the fire.

One person was taken to Bayhealth Hospital’s Kent Campus, treated for various cuts and lacerations and then released, Chionchio said. The individual was not a firefighter, he added.
