An internal Garda disciplinary inquiry has recommended that two armed gardaí who got drunk while on protection duty at the US Embassy be sacked.

The two went drinking and subsequently fought outside the pub and at the US Embassy while watched by civilian security staff and US marines.

One of them subsequently handed over his gun to a uniformed Garda and drove home but was arrested and subsequently convicted of drink driving.

A file was also sent to the Director of Public Prosecutions who directed no charges against either man.

Garda Headquarters set up an internal inquiry with one man facing five charges and the other seven in relation to breaches of discipline and dereliction of duty.

Both were found guilty on all counts and the board has now recommended to the Commissioner that both men be dismissed.
