Powder Springs Police Major Michael Cochran was chosen Monday as the city’s interim police chief by the City Council during a special called meeting.
Cochran replaces Police Chief John Robison on Jan. 1 as Robison returns to the Alpharetta Public Safety Department, where he served from 2001 to 2011.
Robison will serve as Alpharetta’s director of Public Safety.
Since February 2015, Robison has served as the Powder Springs police chief and, since 2011, on the city’s police force.
Robison, who will begin his new role Jan. 3, will lead police, fire, 911 and emergency management services, heading a department of 262 positions.
He will replace Gary George, who will end his 46-year law enforcement career at the end of January.
George came to Alpharetta in 2001 as police chief and led the merger of the city’s police, fire, communications and emergency services into a unified public safety department.
