A crossbow has been recovered after the deaths of three family members of a BBC racing commentator.

Triple-murder suspect Kyle Clifford, 26, is in a serious condition in hospital after he was found with injuries in the Hilly Fields area of Enfield, north London, on Wednesday, Hertfordshire Police said.

Carol Hunt, 61, the wife of BBC 5 Live commentator John Hunt, and two of their daughters, Hannah, 28, and Louise, 25, were found fatally injured at a house in the quiet cul-de-sac of Ashlyn Close in Bushey, Hertfordshire, just after 7pm on Tuesday.

Clifford, who was the subject of a manhunt for a number of hours on Wednesday, is yet to speak to officers about the incident, the force added.

Police confirmed they had received no earlier reports after exploring whether there had been previous contact with Clifford or the victims.

Detective Superintendent Rob Hall, from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit, said: “Our thoughts remain with the victims’ family and loved ones at this devastating and indescribable time. They are being supported by specially trained officers.

“This was an unprecedented attack and we are determined to understand the full circumstances of what happened that evening and the events leading up to it.

“This investigation, as I’m sure people can imagine, will take time.

“I’d like to reiterate my sincere thanks to the members of public who contacted us yesterday and helped with our inquiries.

“We are still appealing for anyone with information in relation to the incident on Tuesday evening in Bushey and activity in Enfield yesterday that could assist us to please contact police directly.”

On Thursday, further searches took place at a house linked to Clifford’s brother, Bradley Clifford, who was jailed for life with a minimum term of 23 years for the murder of moped passenger Soban Khan in 2018.

According to the Metropolitan Police, at the time of the murder Bradley Clifford had targeted the moped before crashing into it, and continued to assault Mr Khan after the collision.

Officers were seen at the address in Rendlesham Road, Enfield, north London, in relation to the deaths.

Police staff wearing gloves and face masks were seen outside the property, which was first searched on Wednesday.
