Update 6.40pm: The Garda Commissioner has not ruled out former senior officers - including her predecessors - being questioned about financial irregularities at the training college in Templemore.
Noirín O'Sullivan rejected claims that she in any way misled the Public Accounts Committee yesterday over how she found out about the problem in 2015.
She said an audit must be completed as well as an investigation by an assistant commissioner.
Noirín O'Sullivan said if any criminal wrongdoing is unearthed it will be followed up.
“That work will help us to identify who, what and where it happened and when it happened. Separately to that assistant commissioner [John] O’Driscoll is looking to see if there are any other issues arising that require further examination and he will also make recommendations to me.
“I can tell you those recommendations will be fully followed through and we will get to the bottom of this.”
Update 4pm: The Garda Commissioner has defended her evidence to the Public Accounts Committee over financial irregularities at the training college in Templemore.
Commissioner Noirín O'Sullivan has insisted the length of the meeting wasn't an issue.
"Under no circumstances did I mislead the Committee.
"The fact is, that as I say, after the meeting of the 27 of July, irrespective of how long it took, immediate steps were taken to address all of the issues.
"We put in place the structures that are now in place in the college, with a principal administrator, a civilian member there, we moved to close down the bank accounts immediately, we've moved to transfer the ownership of the lands," she said.
Earlier: Sinn Féin's Mary Lou McDonald has promised to have the Garda Commissioner back before the Public Accounts Committee within a couple of weeks.
Norin O'Sullivan has been heavily criticised after a senior civil servant contradicted her evidence to the Committee yesterday about financial troubles at the Garda training college.
Ms O'Sullivan claims she learnt of irregularities during a 'brief' exchange over a cup of tea.
While the Garda's HR head says they held a detailed, two hour discussion.
PAC Committee member Mary Lou McDonald is determined to get to the truth: "It's now our job and we will have the Garda Commmissioner and all of the witnesses back before us within a couple of weeks.
"We have looked for a series of correspondance and documentation because believe you, me, we will get to the bottom of this.
"And we need to establish in regard to that particular meeting, who was right and who was wrong."
