Just one day after being arraigned on assault and weapons charges, Eminem has been hit with more weapons charges stemming from an alleged altercation with a member of the Insane Clown Posse's entourage.

Em, real name Marshall Mathers, was interviewed, booked, and arraigned in Royal Oak, Michigan's 44th District Court on Thursday and is now facing one felony charge of carrying a concealed weapon and a misdemeanor charge of brandishing a firearm in public. The misdemeanor charge carries a maximum sentence of 90 days, while the felony charge carries a maximum sentence of five years.

Oakland County Chief Deputy Prosecutor John O'Brien told MTV News that the charges stem from an incident that is alleged to have occurred at a car audio store in Royal Oak, Michigan on Saturday afternoon. Prosecutors claim that Em became involved in an argument with Douglas Dail, who works within the Insane Clown Posse's camp. Prosecutors charge that Eminem dropped his handgun during the heated exchange, picked up the gun, and continued to brandish it while arguing with Dail. O'Brien also said that prosecutors consider Em to have been the "initial aggressor" in the altercation.

Spokespeople for the Insane Clown Posse's management would not comment on the matter except to confirm that Dail is an employee of Psychopathic Records, the label that ICP started in 1991 with manager Alex Abiss.

Prior to this alleged event, Em and ICP (both products of Detroit) had reserved their attacks for their albums. ICP had referred to Em as "Slim Anus" on a track, while Eminem staged an extended oral sex skit involving ICP on his new album, "The Marshall Mathers LP".

Prosecutors note that a complaint was filed the day of the incident and are calling Dail a "reluctant witness" in the case. O'Brien also said that prosecutors are charging Em with brandishing a weapon and not a more serious charge, because the rapper allegedly did not threaten Dail with the weapon.

Spokespeople for Eminem's label, Interscope Records, confirmed his latest arrest and released a statement declaring, "We are confident that the charges will be favorably resolved as soon as possible." Interscope went on to say that they feel the charges will not keep Em off of the upcoming "Up In Smoke" tour, which begins on June 15 in San Diego.

A warrant was issued for Eminem's arrest on Thursday morning, and the rapper voluntarily surrendered to authorities on Thursday afternoon. The rapper is now free on a $10,000 bond.

Em faces a court date on the new charges on July 7. The "Up In Smoke" tour is slated to be in Detroit on July 6 and Auburn Hills, Michigan on July 7.

If prosecutors' claims are correct, Eminem had a very busy Saturday. Hours after the incident with Dail is alleged to have taken place, prosecutors claim Eminem also got into a squabble with his wife, Kimberly Scott Mathers, and another man at a Detroit-area nightclub. The incident ended with the rapper facing felony charges of assault with a deadly weapon and carrying a concealed weapon without a license. In that case, Em is accused of brandishing a handgun and threatening to kill someone else, though the gun was not loaded.
