Garda Commissioner Fachtna Murphy and other senior officers are to hold talks with senior banking officials tomorrow to reiterate safety protocols after Friday's robbery of the Bank of Ireland vaults at College Green in Dublin.
Seven people are still being questioned in connection with the "tiger kidnapping" and theft of €7.6 million from a Bank of Ireland vault in Dublin city centre.
Gardaí have recovered a large portion of the cash in the Dublin suburbs of Phibsboro and Blanchardstown.
Minister for Justice Dermot Ahern expressed his concern at the circumstances surrounding what was the biggest robbery in the history of the State.
Mr Ahern said protocols agreed between the banking sector and Garda stated that in the event of a kidnap situation, no money should be taken from any bank facility before gardaí were alerted.
He said because that protocol was not followed in relation to Friday's raid, gardaí had no time to put a rapid reaction operation in place. "I would be less than frank if I didn't say that there are issues of concern in relation to how this happened and how it was allowed to happen," he said.
Two women and a five-year-old boy were kidnapped at gunpoint and tied up by the north Dublin gang. One of the women was also beaten. The bank official forced to steal the money, Shane Travers (24), was told to bring the cash to Clontarf Dart station in north Dublin.
Six men and one woman were arrested by gardaí.
They are members of a well-known gang from Dublin's north inner city and are connected to a major Dublin gangland figure.
One man was arrested following a car chase car on the M50 close to the Navan Road shortly after 9.30pm last night. The six other people were arrested in the Dublin 7 area later the same evening.
Gardaí discovered what they call "a substantial quantity" of cash in the course of the series of arrests. They also seized six cars.
The six men and one woman who range in ages from early 20s to late 30s are being held in Blanchardstown, Bridewell, Finglas, Mountjoy and Pearse Street Garda stations under Section 30 of the Offences Against the State Act.
