A teen killer has sparked outrage with a violent rap song about a gangland hitman which was filmed in a Scots prison and posted on TikTok.
Byron Cooper is one of five inmates at HMP Shotts, in Lanarkshire, who staged the two-minute video which glorifies violence, drugs and misogyny.
Cooper, who was jailed for life in 2010 for murdering a retired Merchant Navy officer when he was just 16, is seen spitting out vile lyrics.
