Irishman Kevin James Mallon and interpreter Barbara Carnieri were each arrested last week for allegedly being in position of over 1,000 fraudalently obtained tickets for the Games.

Mallon was detained for illegally reselling tickets at inflated prices and faces charges of false marketing, while Carnieri was accused of false marketing.

Both were employees for THG Sports, the Authorised Ticket Reseller (ATR) in Ireland for London 2012 and Sochi 2014.

Another company, Pro 10 Sports Management, are the ATR for these Games, however, meaning THG Sports had no rights to sell or allocate any.

Many of the tickets seized were official OCI-allocated ones, however.

"The OCI is conducting a full and robust inquiry and is awaiting information and evidence from the Rio investigating authorities," Hickey told insidethegames today.

"When we have a clearer picture on what has happened, I will be more than prepared to explain to the Public Accounts Committee and any other public organisation."

The OCI have "formally requested the Rio 2016 Organising Committee to pass on immediately all evidence and relevant information from the investigating Brazilian authorities to enable the OCI to advance our inquiries as quickly as possible".

But this response has been branded as a "joke" by the chairman of the Public Accounts Committee in Ireland.

"They are saying they are treating the matter seriously and if anybody is found to have breached the regulations they shouldn't be appointed for future Olympics," Seán Fleming told RTÉ.

"That's a joke, there has to be stronger sanctions than that."

THG Sports have denied the allegations made against company director Mallon, claiming they are "seeking an urgent review of the case by the Brazilian judiciary and is seeking Mr. Mallon’s release".

He is expected to face charges over the next few days.

THG Group is owned by Marcus Evans Group, which also controls English football club Ipswich Town.

Fleming also called on OCI President Pat Hickey to immediately make a "complete and full" public statement 

"He must have a good idea of where the breakdown in the system in relation to the ticket allocation sales and resale occurred, so I think he could give a bit of clarification on that at this stage because Ireland is getting bad publicity internationally and we could do without that...and he should help put it to bed as soon as possible," he said.

"The Irish good name has taken a hit internationally over the last couple of days in relation to this issue and it's all well and good to come up with a report next Christmas when everything is forgotten about.

"So, I think, we need to diffuse it because it is going to run during the course of the Olympics and we need to get it off the agenda."

They do not, however, have the authority to summon Hickey to speak before the Public Accounts Committee.
