The owner of a killer bull that took the life of a 63-year-old man in Stanford on Soar, Nottinghamshire, on Friday, has spoken out about his “shock” at the incident.

The victim died at the scene and his 67-year-old wife, who flagged down a motorist for help, remains critically ill, but stable, in hospital.

The bull’s owner Paul Waterfall, of Underhill Farm, said he and his family were shaken by the “tragic incident”.

“My family and I are deeply upset by what has happened,” he said.

“Our thoughts are with the couple’s family at this time.”

Exactly why the bull attacked the couple, who have not yet been named, is unclear but it is understood 61 heifers and a bull are kept in the field near where the attack took place.

Police said the couple had been in the livestock field as darkness was falling when the bull attacked.

The animal was contained by the farmer and put down.

The couple’s two sons travelled to be at their mother’s bedside in Nottingham’s Queens Medical Centre on Saturday.

A post-mortem examination of their father’s body is expected to take place early next week.

Police and the Health and Safety Executive are investigating the incident.
