Zurich-based FIFAexternal link, the world football governing body, has been mired in corruption scandals in the past few years. It is currently the subject of an investigation by Switzerland's Office of the Attorney Generalexternal link. The office has criticised the release of the German report.
"Publication of respective reports does increase the risk of collusion," the office said in a short email statement to swissinfo.ch on Friday evening.
“Therefore, the Office of the Attorney General deeply regrets its publication.”
