FOX4 New Kansas City reported that no reason was given for the dismissal of the charges, with the court stating that it was a confidential matter.
Carey was arrested in December 2021 and charged with misdemeanor assault after an alleged altercation with a security officer at Kansas City International Airport.
Video of Carey's arrest that was shared by TMZ showed the legendary drummer urging a bystander to "videotape all of this," then getting handcuffed by police outside the terminal. Officers pushed Carey against a glass wall, with one ordering him to "quit resisting now."
Carey was booked for misdemeanor assault and released on bond. Neither he nor Tool has commented publicly on the incident.
A day before his arrest, Carey was in his hometown of Lawrence, Kansas, sitting in with the University of Kansas band for a Jayhawks basketball game.
