A suspect in the killing of an Irish barman has been released from custody by a panel of judges in a Dutch court.

Damian Mooney, 26, was stabbed to death in Amsterdam last August during what was described as a frenzied attack while he was returning from a nightclub.

The 27-year-old suspect, who has not been named by police, was released when the court decided there was not enough evidence against him to proceed with a manslaughter or murder trial.

However, a spokesman for the Dutch public prosecutor's office said the man was still regarded as the chief suspect and that the police investigation would continue.

The suspect, who is a Dutch national of Surinam origin, had been held for 14 days.

Mr Mooney, originally from Kilkenny, died of stab wounds on 28 August. He had been a barman in O'Donnell’s Irish pub.

Police arrested the man after they were given CCTV footage by a company with offices near the murder scene.

It apparently showed the two men walking together. According to reports, Dutch police say the suspect admitted meeting Mr Mooney, but denied having anything to do with the attack.
