Police Commissioner Ray Kelly sent out a final goodbye to New York’s Finest in a message sent out to police personnel across the city on Monday night.

“As my time as police commissioner comes to an end, I want to thank you for the outstanding work you have done,” Kelly said in the missive, “A Finest Message,” sent out at about 11 p.m.

Noting that the NYPD has been on the “front lines” of the war against terror since 9/11, he said, “You did not give an inch against crime. It decreased more than 30 percent since 2001.

“I wish you nothing but the best in the future.”
