A criminal gang leader has been convicted of the possession and supply of almost €1m worth of heroin, which was seized in Dublin almost five years ago while he was in prison...

The three judges of the Special Criminal Court ruled today that a drugs tick list sent by text, along with notes found in his cell, amounted to directions for the distribution of the 5kg of heroin.

It is the first time a drug dealer has been convicted of running his business from inside prison.
