Pat Hickey has been denied bail by a judge in Brazil as he faces allegations regarding the illegal resale of tickets for the Olympics.
After being admitted to the Samaritano Hospital, Mr Hickey was discharged and driven by the Civil Police to the Carlos Eboli Criminal Institute in downtown Rio, according to reports by RTE.
Hickey has since been moved to a police processing centre and the issue is expected to be escalated to Polinter, an inter-state investigations unit.
