AN initial reward offered by the owners of a pregnant mare which died with its unborn foal after a horrific attack in a field near Gainsborough has been more than doubled.
Breeders Graham and Gill Worrell, who run the business at Prospect House Farm in Gate Burton with son Rupert, initially offered £1,000 for information leading to a conviction.
They were sickened by the overnight attack on 19-year-old chestnut mare Persian Dream.
Now the reward has been increased to £2,500 – because the family are determined that whoever committed the crime should face justice.
The attack took place in the field off Clay Lane between 9pm on Thursday, May 3 and 6am the following morning.
No arrests have been made, but the investigation is ongoing.
The Worrells believed at the time that the horrific mutilation of the animal could have been the work of Satanists because of its 'ritualistic' nature.
And they were so angry – having bred and sold pedigree horses for nearly five decades – that they offered the reward for an arrest and subsequent conviction.
The distressed foal died within hours of the crime's discovery – and the mother passed away within a day due to shock and massive internal bleeding.
"She was so horrifically damaged that the attack defies description," said 67-year-old Mr Worrell senior.
"I've been breeding horses very successfully since I was 18 and I've never known anything like this. It was just unimaginable, I hate to think of her suffering so much. It was just plain murder of a defenceless animal."
Rupert, 41, said he believed the horse had been killed as some kind of Satanic ritual.
"Persian Dream was such a calm mare she would have allowed anyone to lead her," he said. "They certainly picked the animal which wouldn't resist an attack. It was like a Satanic sacrifice.
"That's why we're offering the reward.
"Whoever did this needs to be caught before they do it again."
Lincolnshire Police wildlife crime officer PC Nick Willey is urging anyone who has information to contact police.
"An initial appeal generated public interest and people were appalled by the attack and the needless loss of life of the animal and her unborn foal," he said.
"The public have been shocked by this attack and despite significant interest in the incident we still need more information to help us catch the person or people who did this.
"The death of the horse and its foal was extremely upsetting for her owners and they are hoping that this reward will encourage people to come forward."
