Murderer Connor Chapman can be heard telling enemies they "will regret it" saying they had "signed their own death" in a rap video recorded in prison.
The footage recovered by detectives from a mobile phone, was not heard by the jury during the trial and was only aired during his sentencing at Liverpool Crown Court where he was told he would spend at least 48 years in prison.
Chapman was convicted of the murder of 26-year-old Elle Edwards in a botched gangland shooting outside the Lighthouse pub, Wallasey Village, late on Christmas Eve last year. Elle was struck in the head by two of 12 bullets fired from a Skorpion sub-machine gun at a group of people outside the pub's front entrance.
