Artie Lange is back behind bars.

The 51-year-old comedian was reportedly arrested Tuesday morning after violating his drug probation. reports Lange was taken into custody at the Freedom House addiction treatment center, where he resides as part of a court-ordered program. Katherine Carter, a spokesperson for the Essex County Prosecutor’s Office, said Lange was arrested "for failing to comply with the terms of his participation in the drug program."

Lange will remain in a correctional facility until he can meet with a judge for re-evaluation. The details of his alleged probation violations were not disclosed; however, Essex County Sheriff Armando Fontoura told Lange "sounded good" and "looked sober" at the time of his arrest.

The former Mad TV star and Howard Stern sidekick was arrested in 2017 for possession of heroine and drug paraphernalia. He was subsequently sentenced to four years in probation, which he violated in early 2019 after he was busted with possession of a controlled substance in New Jersey. Lange's camp issued a statement on his official Twitter page, announcing the comedian had entered rehab.

"Excuse any show advertisements.. starting today, Artie will be undergoing a long term treatment program, he loves and respects his fans… updates coming soon.. and it’s time," read a since-deleted tweet.

Lange was spotted last week at a New Jersey gas station where was working as part of a rehab program. He told a fan he only had "10 more days, and then I’m satisfying the program, I think." He then promised to return to the comedy stage "soon."
