A man with a history of “incredibly sadistic and violent behaviour” has been jailed after gardaí caught him attacking his mother.
Blaine O’Mahoney (26) was jailed in December 2005 for pouring flammable liquids over a homeless man and setting fire to him. Judge Frank O’Donnell sentenced O’Mahoney to 11 years with the final year suspended. He said at the time that without a drastic and radical change O’Mahoney would continue to be a “serious threat to society”.
Yesterday Judge Martin Nolan sentenced O’Mahoney to five years for producing a knife during the incident with his mother and threatening gardaí with a broken bottle in a second incident.
O’Mahoney of Swan Grove, Ranelagh, Dublin, pleaded guilty at Dublin Circuit Criminal Court to production of a knife at Oak Court Lawn, Palmerstown, on September 26th, 2010 and production of a glass bottle on February 2nd, 2011.
