Two Oireachtas committees agreed to waive parliamentary privilege earlier this week so as to enable gardaí to seize a laptop from a man working for a TD.

In a statement, the gardaí said: "Gardaí are currently investigating allegations made against a male relating to the viewing of child abuse material online contrary to the provisions of Child Trafficking and Pornography Act, 1998."

The two committees were the Dáil Committee on Parliamentary Privileges and Oversight and the Seanad Committee on Parliamentary Privileges and Oversight.

In a statement, the Houses of the Oireachtas said: "We are not in a position to comment on the confidential proceedings of the Committee on Parliamentary Privileges and Oversight of either House."

Gardaí are understood to have been required to make the request to the Dáil and Seanad committees because the laptop had been issued by the Oireachtas.

The TDs and Senators on both committees were not informed of either the nature of the alleged offence, or any names.

The man under investigation works for a TD who is not accused of any wrongdoing.

The Dáil CPPO gave its agreement on Tuesday, with the Seanad CPPO following suit on Wednesday.

Both committees were informed that the TD had given their consent for garda access.

They followed suit after a warrant was furnished by the gardaí.
