Ray Whelan, who works for ticketing agency Match Services, was one of 11 people taken into custody last week, but was later released without charge.
However, the case has taken a new twist as Whelan is being treated as a fugitive after absconding from his hotel in Rio de Janeiro.
The Briton's passport is being withheld as the investigation remains ongoing, and he was due to be re-arrested at the Copacabana Palace hotel before he fled.
"He's now considered a fugitive," said investigating officer Fabio Barucke. "We have security camera images of him exiting the hotel through a service door."
Match Services deny any wrongdoing and Whelan previously pledged to cooperate with the investigation, stating that he is confident of being exonerated.
