Garda Brendan Phillips (34), who is alleged to have taken €450 in fraudulent bank machine withdrawals, had the case against him adjourned at Dublin District Court.

The former Sligo and Eastern Harps Gaelic footballer is facing a two-day trial which will involve CCTV evidence as well as 25 prosecution witnesses.
A State Solicitor, Rioghnach Corbett asked for the case to be mentioned before the trial date as there is one more charge to be proffered.
Judge Bryan Smyth adjourned it to a date next week, when the additional charge will be brought. The trial at the non-jury court will take place later this month.
