Minneapolis Police Chief Tim Dolan announced Wednesday he'll retire at the end of the year.
Dolan said in a memo to City Council members that he would not seek a third three-year term.
He joined the Minneapolis Police Department 29 years ago and assumed leadership roles in narcotics and emergency response before Mayor R.T. Rybak nominated him for the top spot. Dolan was sworn in as chief in 2007.
Rybak and some council members credit Dolan for making the city safer, and for leading efforts to root out illegal guns.
"He led a historic drop in crime," Rybak said. "It was led by decreasing juvenile crime and getting illegal handguns off the street, which were two huge goals of ours. He's been a fantastic partner with me and with our communities."
But Dolan also has his share of critics. A citizens panel that investigates police misconduct last year voted that it had no confidence that the chief would properly discipline misbehaving officers.
Some City Council members have also said Dolan needs to do a better job of managing his department's budget.
In a statement, Dolan said he was honored to have served the city, but it is, "time to move on to the next stage of life."
