After working without a contract for more than two years, Minneapolis police officers have reached a tentative pay deal with the city.

The agreement, details of which are unknown, brings to an end months of back-and-forth negotiations between Minneapolis and the union that represents about 860 cops. The last contract expired in December 2014.

The accord still requires approval by the Executive Committee, which could come as early as its meeting Wednesday, as well as the go-ahead from the Public Safety committee and, eventually, the full council.

Minneapolis police Chief JaneƩ Harteau said in a statement that union and department officials worked "very hard in good faith to find common ground, which I believe will allow the MPD to serve its residents more effectively and more efficiently."

"While I am not willing to offer specific details prior to our conversations with council members, I do believe the agreement allows for greater flexibility and fiscal responsibility," Harteau said. "At the same time, it also allows us to better care for our hard working officers."

Lt. Bob Kroll, president of the Police Officers Federation of Minneapolis, said Friday that he was prohibited from discussing the specifics of the tentative pact because of a nondisclosure agreement.

But, in an editorial published last May in the Star Tribune, Kroll voiced his frustration at the lack of a new deal, pointing out that officers had been working without a contract for more than 16 months. City leaders, he wrote at the time, "led by extreme leftist interests, are systematically trying to dismantle the Minneapolis Police Department."

Kroll previously called for paying officers better wages, to not only encourage higher-quality job applicants and increase diversity, but also to retain officers who might be lured away by better-paying departments.

Mayor Betsy Hodges, who in the past has voiced her support of altering the police contract to address misconduct, declined to comment.
