Ken Thompson has been elected district attorney in Brooklyn, defeating longtime incumbent Charles “Joe” Hynes, who refused to accept defeat after a bruising Democratic primary.

With 58 percent of precincts reporting Tuesday, Thompson was leading with 72 percent of the vote.

The 48-year-old Thompson will be the borough’s first black district attorney. He beat Hynes during the Democratic primary in September, the first time in a century a sitting district attorney was ousted. Hynes then campaigned as a Republican.

Thompson is a former federal prosecutor. He said he wants to change the culture of the office and bring in new technology. It’s of the nation’s busiest prosecutor offices and handles more than 80,000 cases a year.
