Roddy Ricch was arrested on gun charges Saturday night, hours before he was scheduled to take the stage at Governors Ball.
The NYPD said the 23-year-old was arrested after a security check of his tour bus revealed a gun under a seat and large capacity magazine.
The Los Angeles-based rapper was in town for this weekend's Governors Ball, where he was set to perform Saturday in a lineup that included Halsey, Tove Lo, Flume, Shaquille O'Neal and more.
"Unfortunately Roddy Ricch is no longer performing today," the festival's official Twitter account announced just after 7 p.m. Saturday.
"The Box" singer was slapped with multiple gun charges, along with two other men from New York.
