The 32-year-old Jonathan Manfre, a childhood friend of "Jersey Shore" cast member Mike "the Situation" Sorrentino, was arrested early on July 24 for "possession of a controlled substance."

Deputy Chief Michael Mohel, who confirmed that the substance was Ketamine, told Radar that his office was still deciding if the case would be presented to a grand jury or sent to the municipal court for adjudication.

According to drugfree.org, Ketamine is a medically prescribed drug that is legally used as an animal tranquilizer. It often causes dream-like states and hallucinations.

Mohel was released from jail on July 24 after posting a $1,000 bail at the Ocean County Jail, according to Radar.
