Hulk Hogan: Gawker Leaked N-Word Story ... They Should Be Jailed

8:13 AM PT -- Gawker is adamantly DENYING leaking the information.

Gawker's President and general counsel Heather Dietrick tells us, "Hulk Hogan has only one person to blame for what he said and no one from Gawker had any role in leaking that information."

Hulk Hogan is on the warpath -- claiming Gawker honcho Nick Denton leaked the story about Hulk using the n-word to poison Hogan's $100 million case against Gawker ... and now he wants Denton thrown in jail.

Hogan just filed new court docs in his sex tape lawsuit against Gawker -- and in the docs, he asks a judge to launch a full-blown investigation into Denton and former Gawker exec A.J. Daulerio to prove they leaked confidential details from the sex tape video, including the n-word story.

In the video, shot in 2012 and published on Gawker, Hogan is seen having sex with a friend's wife in a private bedroom. In an unpublished part of the tape, Hulk goes on a racist rant ... using the n-word multiple times.

In legal docs, filed in a Florida state court, Hogan claims the judge in his $100 million lawsuit deemed the n-word portion of the video "confidential" -- and blocked all parties from making it public.

Now, as Hogan's case against the media outlet is nearing trial, Hulk says he believes Gawker leaked the n-word story to ANOTHER media outlet last week because they knew it would make Hogan look bad and damage his case against them.

In the court docs, Hulk says if an investigation proves his suspicions -- he wants anyone involved in leaking the story LOCKED UP ... and he also wants the judge to automatically declare him the winner in the $100 million lawsuit.
