FLINT, Mich. -

Lawyers for hip-hop duo Insane Clown Posse have filed a lawsuit in Michigan seeking documents that would explain why the FBI considers its fans a gang.

The lawsuit in Flint federal court says the FBI failed to timely respond to a 2011 request under the Freedom of Information Act. Insane Clown Posse fans are known as Juggalos.

In 2011, the FBI included Juggalos in its national report on gangs.

The report doesn't mention a direct connection to Insane Clown Posse, but says many Juggalos have "gang-like behavior" and commit crimes and violence.

The report has a picture of a Juggalo wearing face paint and aiming a gun.

Detroit FBI spokesman Simon Shaykhet declined to comment Wednesday.
