Jack Warner, one of the FIFA officials indicted on charges stemming from a U.S. corruption investigation last week, has pledged to unleash an “avalanche” of information about the conduct of international soccer's governing body, in a television appearance Wednesday.

In a speech that aired as a paid political announcement on TV, in Warner's native Trinidad and Tobago, the former soccer executive claimed that he “feared for [his] life,” and that he possessed documents that linked FIFA to the 2010 elections in his home country, according to the Independent.

Warner added that he will "no longer keep secrets for them who actively seek to destroy the country."

Warner, who denies charges including racketeering conspiracy, wire fraud conspiracy, wire fraud, money laundering conspiracy and money laundering, also alleged in his address that he had handed documents to lawyers that "also deal with my knowledge of transactions at FIFA, including -- but not limited to -- its president, Mr. Sepp Blatter."

Blatter resigned his post as president of FIFA this week, just days after being reelected for a fifth term. The organization has been rocked in recent weeks by the arrest of several senior officials and former officials on corruption and related charges brought by U.S. authorities.

Despite his claims to fear for his life, Warner said: “Not even death will stop the avalanche that is coming. ...The die is cast. There can be no turning back. Let the chips fall where they fall.”

Warner has not produced any documentation to support his allegations, and neither FIFA nor Blatter have commented on the allegations he made, according the Guardian. Warner's claims emerge just hours after documents from a 2013 U.S. legal proceeding, which showed that former FIFA executive Chuck Blazer had admitted to accepting bribes.

Warner claims that he emailed Blatter to "empathize" over his FIFA resignation, though he said the Swiss should leave immediately rather than stick around to potentially "cook the books" before his departure, the Telegraph reported.
