He resigned from Sinn Fein over the weekend
Its expected Brian Stanley will be asked to stand down as Chair of the Public Accounts Committee.
He resigned from Sinn Fein over the weekend, claiming he'd been unfairly treated during an internal inquiry, which he described as a 'kangaroo court'.
Sinn Fein Leader Mary Lou McDonald has confirmed the complaint has been passed on to Gardaí, and has referred to Deputy Stanley's comments as "pure deflection".
The party leader says the initial complaint at the end of July was "absolutely appropriate for the party to enquire into".
