Paul Bulman, 26, directed the lucrative operation using hidden mobile phones from his prison cell at HMP Edinburgh. His gang pedalled the stimulant pentedrone with £500,000 of the designer drug shipped in from Holland.
But, his crime network was smashed when members of his clan were snared by watching detectives. Bulman, of Knightswood, Glasgow, is back in prison after he pled guilty to being concerned in the supply of pentedrone. He is due to be sentenced next month.
