British organizers say employees of Rio de Janeiro's 2016 Olympic committee stole files from London's organizing body during the 2012 Games.
The incident involved Rio employees who were working alongside London organizers in the technology department. They allegedly downloaded London documents without authorization.
London organizing committee spokeswoman Jackie Brock-Doyle tells The Associated Press that "files were accessed and removed without our permission."
She says the "Rio team acted swiftly to resolve the issue and return the files."
The Rio employees involved were removed from the London program.
Brock-Doyle responded to a report in the Brazilian media that nine Rio employees had been fired over the incident.
