On Friday, they created a shrine to Damond outside the Minneapolis Police Department's 5th Precinct, replete with candles and two-dozen roses, to protest "her Somali-born killer - whom a judge recently decided not to charge".
The tribute included candles, flowers, framed photos and cards that read, "United We Stand".
Elder told the Minnesota Public Radio News, "We can not allow any memorial and anything like that to be put up at that location".
Damond was shot and killed in July by a Somali police officer after she called 911 to report a possible assault behind her house.
Spokesman of the police department, John Elder said when the department came to know about the memorial created outside the police department, an officer cleared it up.
The group helped organise participants in the deadly white nationalist rally in Charlottesville, Virginia in August.
In the video Mr Freeman criticised investigators for not doing "their jobs" and revealed the key witness in the fatal shooting, Officer Noor's partner Officer Matthew Harrity, had offered little insight. People just don't respect white supremacist shrines like they used to.More news: Korean Officials Allegedly Involved in Ballistic Missile Program
"I condemn the perpetrators and their tactics in the strongest possible terms", Frey said.
It was condemned by police and local mayor-elect Jacob Frey and has now been removed. However, the officer was not charged and no case was filed against him.
Damond, who was struck in the abdomen, died at the scene. A memorial past year honoring the death of Kate Steinle, who was fatally shotwhile on a stroll with her father in San Francisco's Embarcadero in 2015, was reportedly created by white nationalists.
The hate group Identify Evropa took credit for the "shrine" honoring Justine Damond outside the Minneapolis police headquarters on its Twitter account on Saturday.
Ms Damond's death sparked outrage in Australia, where Prime Minister Malcolm Turnbull called it "inexplicable" and "a shocking killing". This statement is disturbing on many levels because it seems to indicate that Freeman wants Noor prosecuted before any investigation is completed.
