Following the news that Minneapolis Police offers were “startled” by a noise before the officer-related shooting death of Australian Justine Diamond, someone is responding. Signs are mysteriously appearing in Minneapolis, warning the public that “Twin Cities Police” are easily startled. So far, at least two of the fake signs have emerged in the streets and look like regular orange construction warning signs.

Twin Cities Police mocked on fake street signs

According to KARE, the signs had a professional paint job and were put up with heavy-duty screws and were in the process of being removed by authorities on Monday.

While it is unknown who placed the signs, they are an apparent reference to the shooting of 40-year-old Diamond by a police officer recently after calling 911 to report a possible attack behind her home.

At the time, one of the officers, Matthew Harrity, had told investigators he had been “startled” by a loud noise when pulling in at the scene. It was his partner, Mohamed Noor, who pulled out a gun and shot Damond through the driver’s door as she approached their police cruiser. The New York Daily News reports there was news of a search warrant which alleged a woman had “slapped” the trunk of the car, but it is unknown if this was the sound that startled the officers.

Investigations continue into Justine Damond’s fatal shooting

Neither officer who responded to the 911 call had activated his body camera at the time of the shooting, and it is currently not known what happened before Noor firing his gun and killing Damond. Noor has reportedly refused an interview with investigators of the Minnesota Bureau of Criminal Apprehension.

However, it has been suggested by his lawyer that Noor may have been worried about an ambush in the alley where they stopped their car.

Police chief forced to resign

The shooting of the Australian citizen, who was to be married next month to her fiancé, Don Damond, shocked the world and brought hundreds of residents out to pray for her and protest the shooting.

In the wake of the shooting, Minneapolis Police Chief Janeé Harteau resigned after Mayor Betsy Hodges has said citizens had lost confidence in her leadership.

Minneapolis Police had released some personal records on Monday relating to Officers Harrity and Noor. The latter reportedly had two open complaints about him. Records also showed Noor had passed several training courses relating to active shooter training and weapons qualifications.
