The RSPCA is investigating after a duck was spotted in a South Yorkshire country park with a crossbow bolt through its head.
The mallard was spotted at Dearne Valley Country Park in Barnsley, and reported to the RSPCA by Barnsley Council.
The RSPCA said officers from the charity attempted to catch the duck without success - but were continuing to monitor its progress.
Anyone convicted of shooting the bird could face a six-month prison sentence and a £5,000 fine, the RSPCA said.
A spokeswoman for the charity said: “Obviously as the duck is still able to fly and is quite mobile it has been difficult for our officers to catch it.
“We are continuing to monitor it and hope to be able to catch it eventually.”
She added the bird appeared able to feed itself still, but officers wanted to treat it before it came to any further harm.
Officers from the charity believe the bolt may have entered the duck’s head through its ear canal.
The RSPCA urged anyone who witnessed the shooting or has information to call 0300 1234 999.
