BOSTON — Newly elected Lowell City Councilor Vesna Nuon has agreed to a $50,000 settlement with the city and something unusual — an apology from a Lowell police officer — in his 2009 federal false-arrest lawsuit against the city.

Attorneys Myong Joun and Jeffrey Wiesner, representing Nuon, released a statement Tuesday in which they said a key factor in the settlement is that the Lowell Police Department has agreed to revise its training on the law of disorderly conduct in the wake of a federal judge’s ruling earlier this year.

“This case was never about money. It was always about the police treating the citizens of Lowell properly and to strive to do better,” Nuon said in a prepared statement. “I love my city. I am glad that the city and its police department has committed to doing the right thing, which is what I was looking for all along.”

Stephen Pfaff, the attorney for Lowell Police Officer Brian Kinney, who was named in the settlement, could not be reached for comment. Lowell Police Superintendent Kenneth Lavallee said he is pleased that the settlement ends the case.

In the lawsuit filed in July 2009, Nuon claimed his civil rights were violated when Kinney arrested him for disorderly conduct during a March 21, 2008, incident at a friend’s home at 174 Hale St. Nuon claims he was treated unprofessionally by the officer and was only arrested after he tried to call the officer’s supervisor to complain.

When Nuon told Kinney he was calling the police, Kinney allegedly responded, “I am the police.” Kinney allegedly threw down his clipboard and handcuffed Nuon, telling him he was being charged with disorderly conduct.

In Lowell District Court the next day, the charge was dismissed upon payment of $200 in court costs.

But in court documents, Kinney painted a different picture of the incident. Kinney states that when he arrived at 174 Hale St., Nuon was standing outside “highly intoxicated.” When Kinney asked Nuon who called the police, Nuon allegedly responded by saying, “No, I did not, no one called and no one wants you here.”

According to court documents, Nuon began yelling that Kinney was “a coward hiding behind my badge” and to “get off his property.”

Kinney said he gave Nuon two chances to stop yelling and when he didn’t, he placed Nuon under arrest.

In March, U.S. District Court Magistrate Judge Leo T. Sorokin agreed that Kinney did not have probable cause to arrest Nuon and that as a result, Nuon’s federal and state civil rights were violated. But Sorokin rejected Nuon’s claim that the city was negligent in its training and supervision of Kinney.

The settlement with Nuon involves the Lowell Police Department providing “additional training, specifically on the topic of disorderly conduct” as part of the department’s in-service training to all officers, attorney Joun said in the statement.

The training will include a study of the elements of the crime of disorderly conduct, recent case law, including a review of the court’s ruling in the Nuon case, Joun said. In addition, Juon said other specific examples and scenarios to illustrate what does and does not constitute probable cause for disorderly conduct will be studied.

Lavallee said he took the initiative to enlist the help of the Cambridge Police Department, which revised its own training in the wake of the arrest of Harvard professor Henry Louis Gates Jr., to partner with Lowell police to provide this training, which has been ongoing since last fall.

The Nuon case was “part of the equation, but not the sole reason” for the additional training, Lavallee said.

Kinney and Nuon have also met face to face in what Lavallee described as a “mediation session.”

Lavallee said, “Both men agreed that this was an unfortunate incident and shook hands.”

The city agreed to pay $50,000 to partially cover Nuon’s attorney fees, which were reduced because of the city’s agreement to provide additional training, Joun said.
