A crossbow has been recovered following 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 is yet to speak with officers about the incident, the force added.
