RICHFIELD — An arbitrator has reinstated a Minnesota police officer who was fired after a Twitter video appeared to show him hitting a Somali-American teen last year.

Richfield police say the arbitrator reversed Nate Kinsey’s termination Wednesday.

The Hennepin County Attorney’s Office and a special prosecutor reviewed the case and declined to charge Kinsey. But the 10-year department veteran was fired after an internal investigation.

Police Chief Jay Henthorne says the city’s weighing appeal options.
