A 38-year-old man has been acquitted of the murder of a man shot dead in a Dublin pub four years ago.

Christopher Zambra of Galtymore Road in Driminagh was found not guilty of the murder of John Carroll by a jury at the Central Criminal Court.

Mr Carroll was drinking in Grumpy Jack's pub in the Coombe on 18 February 2009 when a gunman wearing a helmet walked in and shot him four times.

The prosecution alleged that Mr Zambra ordered the killing.

An accomplice who had been involved in the murder, but is now in the witness protection programme, was granted immunity and gave evidence claiming Mr Zambra was behind the killing.

Joseph O’Brien admitted he bought the balaclavas and sourced the motorbike used in the gangland murder.

The judge told the jury that Mr O’Brien was a serial liar, a perjurer and was guilty of murder.

The jury saw CCTV footage of the arrival of the motorbike to the pub and of the shooting itself.

The motorbike pulled up outside and the passenger went inside and immediately identified Mr Carroll.

He shot at him with a pistol and Mr Carroll darted across the pub in an attempt to escape.

He was shot a number of times and died later in hospital.

After two months of evidence the jury deliberated for four-and-a -half hours over two days before finding Mr Zambra not guilty of murder.

A relative of Mr Carroll shouted abuse at the eight men and four women after they delivered the verdict.

Mr Zambra hugged his legal team and left without making any comment.
