Hulk Hogan is taking his sex tape fight to the big dogs -- contacting the FBI this week to help him track down the low-life who leaked his naked fun time footage to the media ... TMZ has learned.
Hulk's attorney tells TMZ, the wrestler had previously attempted to file a police report in Florida -- but local police couldn't help him for two reasons:
1) Because the tape was recorded in 2006, the four-year statute of limitations had expired on the offense of unlawfully recording Hulk without his permission.
2) The other offense -- distributing the illegal footage to the media -- crosses state lines, so it's a federal problem ... not a local one.
As a result, Hulk's lawyer says he has contacted the FBI to track down the sex tape leaker ... and bring that person to justice.
We're told Hulk plans to meet with FBI agents on Monday.
