The board of the Olympic Council of Ireland is meeting today to discuss the fallout from the Rio ticketing scandal.

The crisis meeting follows a turbulent week for the Olympic Council of Ireland, with the arrest of former OCI president Pat Hickey in Rio.

He is in jail in Rio as Brazilian police investigate allegations that part of the OCI's ticket allocation was illegally resold.

That prompted the government to set up a non-statutory inquiry to investigate allegations of ticket touting.

A retired judge is expected to be appointed this week to oversee that investigation which Sports Minister Shane Ross says could take about 12 weeks to complete.

The Tánaiste and Justice Minister Frances Fitzgerald says she hopes the inquiry will uncover all the facts behind the case.

The OCI has said it will also appoint an external independent firm to carry out a review into the matter.
