William Hynes and John Mangan were key figures in the organised crime group run by Martin 'Marlo' Hyland, who was shot dead in Finglas.Two senior members of one of the country's biggest criminal gangs have been sentenced to 12 and 14 years in prison after they were caught overseeing the delivery of over €2m worth of drugs.Mangan was on bail when he was caught, so today's 14 year sentence is consecutive to another 14 years he was given last year for drug trafficking.Hynes also has a previous conviction for drug trafficking and was only out of jail one year when he was caught for this offence.The two are among 28 people targeted by the garda operation 'Oak' who have been brought before the courts.At the Dublin Circuit Criminal Court today Judge Pat McCartan congratulated the gardaí on the success of what he called 'a very carefully orchestrated undercover operation'.
