MIAMI GARDENS, Fla. (AP) - The police chief in Miami Gardens has resigned amid allegations that officers routinely harassed and intimidated people at a local convenience store.
The Miami Herald reported ( ) that Chief Matthew Boyd submitted his resignation Wednesday, one day after the NAACP called for a Justice Department investigation into possible civil rights violations.
The NAACP said some patrons of the 207 Quickstop store were arrested hundreds of times for little cause. The store's owner had installed surveillance cameras that captured some of the incidents, which were later made public by the Herald.
Boyd had planned to retire in January. The Miami Gardens city manager says a search is being launched for a replacement.
The owner of the convenience store has filed a federal civil rights lawsuit against the city and numerous officials.
