A Wisconsin man has been arrested on suspicion of cutting off a woman's finger and drinking her blood in an apparent ritual ceremonial. Jonathan Schrap, 24, of Green Bay, has been identified due to his tattoos as being a Juggalo, the name given to the hugely dedicated fan base of rap duo Insane Clown Posse, also known for wearing clown make up.

According to police report seen by Wbay, Schrap is accused of staging a "ritualistic memorial" which involved drinking the blood of his friend Shelby Neuens to commemorate a fellow Juggalo member who died one year ago.

According to police, the ritual was performed by Schrap, Neuens, childhood friend Nick Laabs and fellow Juggalo Preston Hyde, who is also a rapper who goes by the name Bloody Ruckus.

The criminal complaint reads: "Shelby [Neuens] had volunteered to let Jon [Schrap] drink her blood. Jon had taken a machete and made an approximate one-inch laceration on her right side forearm. She was bleeding profusely... Jon filled up a shot glass with her blood and drank her blood."

Neuens is then reported to have volunteered to allow Schrap to amputate her little finger with the machete, telling police she had not drunk alcohol or taken drugs on the night in question. The complaint adds: "Jon then placed the finger in his freezer where he said he would cook it and eat it later. The group then attempted to stop the bleeding by using a car cigarette lighter which failed. They then used a blowtorch."

Schrap was arrested after Neuens's mother overheard her talking about her injuries to her boyfriend. She said she didn't want to press any charges because her injuries were voluntarily.

Scharp is due to appear in court on 21 September accused of mayhem and causing reckless injury.

In 2011, Juggalos gained worldwide notoriety after the FBI described them as a "loosely organised hybrid gang" who exhibit "gang-like behaviour and engage in criminal activity and violence".

In 2014, the Michigan-based rappers Shaggy 2 Dope and Violent J, also known as Joseph Utsler and Joseph Bruce respectively, launched a lawsuit against the FBI saying their fans had been unfairly discriminated against since the FBI listed them on their website as a gang.

The band's infamously obsessive fan base was the subject of a 2014 documentary Whoop Dreams, which focused on the band's annual Gathering of the Juggalos music festival.
