Christopher Zambra has been found not guilty of murdering John Carroll in Grumpy Jacks pub in 2009.
The 33-year-old, with an address at Galtymore road in Drimnagh, has been on trial for the last ten weeks.
John Carroll had been drinking with friends in Grumpy Jacks pub in the Coombe February 18, 2009.
Earlier in the trial, the jury was shown CCTV footage of the night he was murdered.
A motorbike pulled up outside, the passenger went in with a gun, a chase ensued inside and Mr Carroll was shot dead.
Christopher Zambra was never accused of pulling the trigger but the DPP tried to hold him criminally responsible on the basis of evidence given by an accomplice turned Garda informer who said he was present when the accused ordered the hit.
But after hearing 10 weeks of evidence, the jury has today returned a verdict of not guilty.
And when they did so, a member of John Carroll’s family rushed the jury box screaming: "You’ve killed my mother and John’s children."
Zambra then left the courtroom and was released from custody.
