Euclid Mayor Kristen Gail has added 30 days to the unpaid suspension of the white police officer recorded on a cellphone repeatedly punching a black man after a traffic stop. The police chief previously suspended Michael Amiott 15 days for the August 12 encounter. The video shows Amiott punching 25-year-old Richard Hubbard III more than a dozen times and hitting his head on pavement several times after Amiott stopped him for a suspended driver's license. The Cuyahoga County Prosecutor's Office has said it's investigating and has conferred with the U.S. Attorney's Office. Hubbard has pleaded not guilty to resisting arrest.
