A terrified mum could hear her son 'moaning' over the phone as three men threatened to cover his face in acid if she did not cover a £500 debt within 15 minutes.
Callum Lawn, 19, Stephen Lawn, 20, and James Geddes, 22, were sentenced to prison over the brutal attack and blackmail which left their victim fearing he was going to die.
Preston Crown Court heard the man's brother also felt his life was in danger when the thugs called and said he would 'get it' if he did not cough up the cash, Lancs Live reports.
