Hulk Hogan Contacts FBI Over Leaked Sex Tape

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.
