text: The Friesians were found in Dolwen, near Old Colwyn, on Friday after eating poisonous tree clippings dumped in a farmer's field.
  North Wales Police said the culprit is described as a heavily built man, aged 50 to 60, with curly brown hair, driving a dark blue pick-up truck.
  Anyone with information can call 101.
  "Apparently he has been dumping clippings over past two weeks. Has to be living/working local to Colwyn Bay," Sgt Rob Taylor, of the rural crime team, tweeted on Sunday.
  A post-mortem examination showed the cows, aged 16 months, died as a result of toxins found in yew and leylandii tree cuttings.
  Sgt Taylor said he was "appalled" by the "atrocious" act of fly-tipping and praised the "impressive" response to his appeal for information on social media.
target: The description of a man believed to be involved in fly-tipping which left three Conwy cows dead has been released by police.
