The former head of the Olympic Council of Ireland (OCI) Pat Hickey says he will fight charges against him "100%".

Mr Hickey temporarily stood down from his OCI role following his arrest on August 17th by police investigating the alleged illegal re-sale of Rio 2016 tickets.

He was released on bail from the high security Bangu Prison on Tuesday.

Mr Hickey's family also met with Foreign Affairs Minister Charlie Flanagan, to express concern over his treatment by the Brazilian justice system.

In a statement after his release, Mr Hickey said: "I will now stay in Rio and my lawyers will proceed to have the charges laid against me set aside as there is no substantive proof of any wrong doing on my part."

Speaking to Independent.ie on the streets of Rio de Janeiro, Mr Hickey said: "You got my statement yesterday, I'm now going to take care of my health."

Asked if he as going to fight the charges against him, he added: "100% - that's why you see my lawyers here.

"I have no comment, except my statement yesterday."

Speaking to the Pat Kenny Show on Monday, his family's solicitor Anne-Marie James claimed Brazilian police have tried to "utterly degrade" Mr Hickey.

Referring to his arrest, she said: "There is a presumption of innocence in the constitution in Brazil, I believe that the police there have flagrantly completely ignored that.

"I think the photographs of a 71-year-old man in a state of undress, I think the videoing of the arrest, I don't know that that's quite normal procedure.

"I think that that was in an attempt to utterly degrade him."
