Nick Ferrari was discussing how violence in jails has been rocketing... and received a call from a prisoner, phoning on a contraband mobile.
Craig is currently serving a 14-year sentence for firearms offences and has a smartphone which was smuggled in for him by a prison guard.
And as Nick was talking about the government's plans to reverse their cuts in prison guards due to the increase in violence, Craig used his smartphone to call in.
Prisoner Calls Nick Over Violence In Jail
This is remarkable: A prisoner calls Nick with a contraband mobile phone to tell of how bad life in jail has become.
Craig said that he sees violence in prison every day. He said: "A lot of the drugs and the contraband - I'd say at least 85% of it - were brought in by civilian staff or prison officers.
"If you see the type of contraband that prison officers are finding, they are not the sort of amounts people could bring in on a prison visit."
Watch his remarkable call above.
