Jurors have heard how a vulnerable alcoholic suffered unsurvivable injuries when his head was punched, kicked, stamped upon following a drunken row about booze.

Kieran Potts is accused of delivering a flurry of punches and kicks to Norman Ryan just minutes after the defendant had become embroiled in a brawl with his father.

Teesside Crown Court heard how the 55-year-old was found covered in blood and unconscious in his Hartlepool flat minutes after Potts had argued with his father Carl.
