A Garda officer who was involved in the violent incidents in Dublin on Bank Holiday Monday has been transferred to other duties. Earlier, Garda Commissioner Pat Byrne said he had viewed the television footage of the disturbances and was 'concerned' about what he saw.

Commissioner Byrne promised that a thorough and professional investigation would be carried out and that all aspects, both criminal and disciplinary, would be examined.

Taoiseach Bertie Ahern has said he fully shared the concerns voiced by the Minister for Justice, John O'Donoghue, about the handling by Gardaí of the disturbances.

Campaigning in County Laois, Mr Ahern said he had every confidence that the matter would be looked by the Gardaí.

Earlier, Mr O'Donoghue said there would be "consequences" for Gardaí who had gone beyond what he called reasonable force.

He said he did not want to pre-judge what had happened until he received a report into the incident.

Mr O'Donoghue said he would "not necessarily" accept the Gardaí's own version of events. He added that the findings of the report would be made public, as far as legally possible.

He was speaking at the launch of Fianna Fáil’s crime policy during which he claimed that it was the only party that could be trusted on crime.

He repeated the party's pledge to recruit 2,000 extra Gardaí and to establish an independent Garda Inspectorate.

He claimed this Inspectorate would have more power than the Garda Ombudsman proposed by other parties.

Both the Labour Party and the Progressive Democrats have said they favour the appointment of such a Garda Ombudsman. Both parties also said they believed the Gardaí should not be asked to investigate themselves.
