A man has died after being shot with a crossbow at his home.
Darrell Farnham, 44, was found at the house in Aylesbury, Buckinghamshire, on Sunday night, Thames Valley Police said.
A post-mortem examination carried out last night found he died as a result of being shot with a crossbow bolt which passed through his body.
A 40-year-old man has been arrested on suspicion of murder in connection with his killing and is in custody.
Police believe there could have been more than one person involved in what police said was not a random attack.
Detective Superintendent Chris Ward, from Thames Valley's major crime unit, said: "This is very much still an open investigation and we are continuing to appeal for witnesses and any information.
"We believe there could be other offenders and so we are currently concentrating on determining exactly what happened on Sunday night.
"A scene watch remains in place and I want to thank local residents once again for their help and patience whilst investigations continue.
"We have a dedicated team working to solve this crime and bring any offenders to justice and I want to reassure residents that this appears to be an isolated crime and not a random attack."
Mr Farnham was found at the property in Belgrave Road, Aylesbury, at around 10.45pm.
He was found inside by officers and died at the scene.
A 37-year-old woman arrested on suspicion of assisting an offender is also in police custody.
