ANOKA (AP) -- The former Chisago County sheriff has pleaded guilty to harassment and misconduct by a public official for stalking and harassing a female employee.

Rick Duncan pleaded guilty to the gross misdemeanors Thursday in Anoka County.

According to the criminal complaint, when Duncan was sheriff in late 2017, he faked a series of letters using the pseudonym ``Control Freak,'' which demanded that he and the employee attend a conference and stay in a hotel room together with one bed. He later admitted to writing the letters and said he suffers from post-traumatic stress disorder.

He's expected to receive four years of probation when he's sentenced Dec. 1.
