The fringe Christian group Westboro Baptist said on Tuesday that it will protest any public service held for 'Jackass' star Ryan Dunn, whose fiery car accident on Monday prompted an outpouring of sympathy and support.

The group, denounced by mainstream Christianity, often exploits funerals to promote what they believe is the will of God, and other political leanings.

In a posting on Westboro's site called Ryan Dunn is in hell!, the group tries to dissuade fans and admirers of Dunn, explaining they could meet the same fate.

WBC will picket any public memorial/funeral held for Dunn, warning all not to make a mock of sin, and to fear and obey God, the group said in a news release.

This arrogant jackass, famous for his vulgar stunts at which this nation snickered, died in a car accident in Goshen, PA (one of the most evil states to ever exist) after tweeting a picture of himself & two friends drinking - just hours before a 3 AM high-speed crash left him & his passenger dead & in flames. This is no prank!

DellaVechia, Reilly, Smith & Boyd Funeral Home, Inc said services and interment for Dunn will be private. A public memorial service will be announced at a later date.

Topeka, Kansas-based Westboro was started by Fred Phelps in 1955 and is best known for protesting soldiers' funerals carrying signs that say God Hates Fags, and Thank God for dead soldiers.

It says on its website that it is an Old School (or, Primitive) Baptist Church, though it has no known ties to any broader national Baptist denomination.

Dunn, the star of slap-comedy TV-shows and movies Jackass, and his passenger died after his speeding Porches crashed and burst into flames.

Alcohol is suspected to have played a part in the Monday death. Dunn tweeted a photo of himself and another man drinking at Barnaby's of America's bar just hours prior.

The Chester County coroner listed blunt force trauma and thermal trauma as the official causes of death for both men. But the definitive answer will take over six weeks as toxicology results return to the labs.

A preliminary examination of the crash site suggested that Dunn's Porsche might have been traveling more than 100 mph in the 55 mph zone when it jumped a guardrail and struck a tree and burst into flames.

West Goshen Township police declined Tuesday to discuss the ongoing investigation.
