Antwan "Big Boi" Patton, half of the Grammy-winning group Outkast, was arrested on Sunday afternoon in Miami on suspicion of drug possession.

TMZ reported that Miami-Dade County Corrections Department said Patton, 36, was charged with three counts of possession of a controlled substance and one count of possession of drug paraphernalia — all felonies. He is accused of having ecstasy pills, MDMA powder and Viagra.

The Los Angeles Times said the 36-year-old was caught by drug-sniffing dogs while getting off a cruise ship.

"While Big Boi was traveling with his group and friends, a small amount of contraband was found in the collective luggage," the rapper's attorney Daniel Kane said in a statement, as reported by the paper. "I am confident when the entire facts are aired Big Boi will be completely exonerated."

Bond was set at $16,000, TMZ said. Patton was booked and later released.
