The interim Garda commissioner says the force is investigating claims that the IRA moved alleged sex abusers across the border into the Republic.
Noirin O'Sullivan's comments come as the Dáil prepares to debate the Republican movement's handling of sexual abuse allegations.
Gerry Adams is expected to come under further fire from other leaders, who believe he and Sinn Féin are hiding information about the movement of abusers.
Up to five hours have been assigned for TDs to debate allegations of sexual abuse against prominent republicans, and the movement's handling of those claims.
This morning the justice minister Frances Fitzgerald said she didn't know if Gerry Adams was capable of supplying any new information but if he did, he must bring it forward.
There are suspicions that that some politicians might use their Dáil speaking time to use parliamentary privilege and make direct allegations against Sinn Fein and the IRA - naming alleged sex abusers who were moved across the border.
