Fire damaged at least three trailer homes in a Bear, Delaware neighborhood Tuesday afternoon and investigators say the blaze was intentionally set.
The fire started around 5:15 p.m. along the 300 block of Glasgow Drive, fire officials said.
Two trailers appear to be a total loss and a third was heavily damaged.
The fire marshal says a person set the fire and also disabled the hydrants which hampered firefighters' response.
A firefighter suffered a burn, but is expected to be fine. Officials are investigating.
