Gardaí in Dublin are investigating an armed robbery at the Bank of Ireland in Clondalkin.

Three armed and masked men entered the bank just after opening time at around 10am and ordered staff to hand over whatever money was in the tills

The men, who were armed with at least one shotgun, escaped with around €3,000.

One person who was in the bank at the time was treated for shock, but no-one was taken to hospital.

The incident is the seventh armed robbery in Dublin and Wicklow in the last five days.

Garda Commissioner Martin Callinan said he is satisfied that the people involved in most of the robberies are known to gardaí.

Commissioner Callinan said that he expects arrests in the next few days.

The recent robberies will be discussed at a meeting between the Minister for Justice and Mr Callinan this week.

The discussions will also address the stabbings at a concert in the Phoenix Park in Dublin two weekends ago.

Earlier, the minister announced that he intends to promote 26 garda officers to the senior ranks.

Mr Shatter said one Assistant Commissioner, four chief superintendants and 13 superintendants are due to be appointed in the next 48 hours.

A series of interviews will be held to appoint at least another eight senior officers to vacant policing positions all over the country.

Fianna Fáil has called for a special task force to be established to tackle violent crime in Dublin.

Sinn Féin has called on the Government to lift the embargo on garda recruitment.
