A 15-year-old schoolboy has been jailed along with two brothers after they beat a security guard to death.
Security guard Christopher Molloy was brutally attacked outside Bootle Strand in Merseyside in July last year.
Liverpool Crown Court heard the 55-year-old was set upon by brothers Jay and Joseph Byrne before the fatal blow was dealt by a 15-year-old, who left him in a critical condition.
