A boss at one of Scotland's biggest prisons has claimed it is 'impossible' to keep drugs out of jails due to massive demand from inmates.
Sean McFedries, head of operations at HMP Barlinnie in Glasgow, said that although 'everything was being done' to prevent drugs being introduced and used behind bars it was 'impossible' to stop all of the drugs getting in.
McFedries, who has held the post since 2018, said a 'substantial demand' for illicit substances saw dealers sell drugs to prisoners at a 'very high' value.
