An Ohio homeowners association has ordered a disabled military veteran to take down a Thin Blue Line flag he flies in his Etna front yard in honor of his police chief son, who was fatally shot five years ago while answering a call.

Thomas DiSario received a letter Monday from Omni Community Association Managers saying the “political sign in the form of a flag must be removed from your property,” WCMH-TV reported.

DiSario has been flying the Thin Blue Line flag in his front yard ever since his son Steven Eric DiSario — at the time the newly appointed Kirkersville police chief — was gunned down May 12, 2017, the station said.
