New Orleans trumpeter Shamarr Allen has been arrested on a charge of battery of a police officer.
The 34-year-old Allen was booked into the Orleans Parish Prison Thursday night after he allegedly struck a deputy in the head at a security checkpoint at Armstrong Park.
Allen had been scheduled to appear at a "Jazz in the Park" event and he allegedly struck Deputy Thomas Elder.
The Sheriff's Office says Deputy Elder was punched "several times" as Allen attempted to get relatives who had no backstage passes through a security post.
Allen is the musician who accused state police of roughing him up during a July traffic stop in the Lower 9th Ward.
