A 38-year-old man has pleaded not guilty to the murder of John Carroll, who was shot dead in a Dublin pub four years ago.

The Central Criminal Court has heard that Christopher Zambra of Galtymore Road, Drimnagh, Dublin, is accused of offering money and ordering the killing of Mr Carroll.

The 33-year-old was killed in Grumpy Jack’s pub in The Coombe on 18 February, 2009.

A gunman got off a motorbike, walked into the pub and shot him a number of times.

The court heard that while Mr Zambra did not go into the pub and did not pull the trigger, he was as guilty as if he had.

Prosecuting Counsel Patrick Gageby told the jury that Mr Zambra advised, ordered and counselled the deliberate killing of Mr Carroll.

The jury was also told that evidence against the accused centres on the evidence of a Joseph O’Brien, who was privy to discussions with Mr Zambra at which Mr Carroll's murder was planned.

Mr O’Brien, the court heard, was an accomplice and a participant, but the DPP has directed that nothing he says in the case can be used against him.

The court also heard that the murder was captured on CCTV, which will be shown to the jury.

The trial continues tomorrow.
