The sister of an armed post office raider recognised her brother during the robbery and identified him to gardaí, a court has heard.
Dublin Circuit Criminal Court heard there were a number of people in the post office in Aylesbury Shopping Centre, Tallaght when the raiders burst in carrying a knife and what was described as a 12-inch double-barrel shotgun.
Shane O'Connor (aged 30) of Brookview Avenue, Tallaght pleaded guilty to robbery of the post office on September 1, 2009.
Detective Garda David Jennings told Mr Noel Devitt BL, the robbery took place on a Tuesday morning which was children's allowance day, meaning the post office was particularly busy.
The raiders, who had their faces covered with scarves, told staff to “fill the f**king bag or I will shoot somebody”.
Between €10,000 and €11,000 was taken in the raid before the gang fled in a waiting Nissan jeep. The vehicle was later discovered abandoned.
After the robbery one of the customers in the shop told gardaí that one of the raiders was her brother, Shane O'Connor.
Ms Caroline Biggs SC, defending, said that Lisa Raferty recognised her brother when he looked straight at her before looking down “in guilt”.
Ms Biggs said Ms Raferty was so disgusted with her brother's actions that she rang the gardaí immediately afterwards.
O’Connor fled to England but was brought back on an arrest warrant in August 2011.
Judge Martin Nolan sentenced O'Connor, who has 25 previous convictions, to four years in prison and backdated the sentence to last August.
His accomplice Derek Evans (aged 26) of Russell Place, Swiftbrook, Tallaght was sentenced to eight years with four suspended last November by Judge Patricia Ryan.
