A Mountjoy prisoner has been convicted of murdering a fellow inmate after a jury agreed with the prosecution case that he had "lured" him into his cell, knocked him to the ground and stamped on his head in a "vicious and unprovoked" assault.

The jury of nine men and three women at the Central Criminal Court took a little less than three hours to return a unanimous verdict of guilty of murder against David Dunne (40), with a last address in Summerhill, Dublin 1
