Airport police responded Sunday to reports of a disturbance between two men. They arrested Carey and booked him at a nearby police station for misdemeanor assault.
Carey was subsequently released after posting bond.
Charges are pending a prosecutor's review of the police report.
Carey, a native of Lawrence, Kansas, spent Saturday taking in a Jayhawks basketball game in his hometown. He drew a roar from the Allen Fieldhouse audience when he sat in with the KU Band for a rendition of Jimi Hendrix's "Fire."
Representatives for Tool and Carey have not yet commented on his arrest.
