A murder trial jury has heard how the victim was stabbed and hacked from head to toe in a "sustained and vicious assault" during which the killer attempted to decapitate him.

A man who was stabbed and hacked to death had regularly beaten his partner and threatened to kill her if she left him, the dead man's neighbour told his murder trial.

A prosecution witness has told a murder trial he heard screaming at around 3am on the morning his neighbour was stabbed to death.
