A video sent to BringMeTheNews shows the scene inside the Minneapolis Fourth Precinct when it was under attack from what the police chief described as "anarchists" early Thursday.
The footage – which the Minneapolis Police Department says is genuine, but was not released by the department – shows what appears to be Molotov cocktails being launched over precinct walls, while gunshots can be heard in the background.
Police Chief Janee Harteau said on Thursday that "anarchists" and people "from outside the community" are believed to be responsible, after they joined in with the protest outside the station.
The precinct has been the scene of a demonstration by Black Lives Matter, NAACP and other activist groups in response to the fatal shooting of 24-year-old Jamar Clark by police. Wednesday afternoon, police arrived to move them off the property.
During a tense standoff, officers used mace and non-lethal marking rounds on protesters, who in turn threw bottles, rocks and bricks at officers and property, causing what Harteau said is tens of thousands of dollars in damage to police vehicles and buildings.
Nobody has been arrested in relation to the Molotov cocktail and gunshots fired, which happened after most of the protesters had gone home, Harteau said.
Rally, vigil Friday
The president of the National Association for the Advancement of Colored People, Cornell William Brooks, is in Minneapolis on Friday where he has been meeting with Gov. Mark Dayton and City Mayor Betsy Hodges, along with other NAACP leaders, to discuss Clark's killing.
He also plans to attend a 4:30 p.m. rally and candlelight vigil outside the 4th Precinct, the Star Tribune reports.
Earlier on Friday, WCCO reported three activists were removed from a Minneapolis City Council meeting after they confronted council members over Clark's killing.
Additional video shows masked men with gun
Black Lives Matter Minneapolis, meanwhile, has raised concerns about another video, featuring two men they said they turned away from the ongoing protest on Thursday evening. (Note: Some language in the video may be considered offensive.)
The video shows the masked men refer to the protesters using a racist term, while one of them said they were "locked and loaded" before brandishing a handgun, saying they were going to "have a look-see" at the protest.
Black Lives Matter said they "left without incident" after being questioned on live video streams by community members.
On Friday afternoon about 3:45 p.m., the Minneapolis PD issued a warning that "a group may attempt to cause a disturbance this evening in front of the Police Department's 4th Precinct," though it is unable to confirm whether this is linked to the video.
"We are asking gathered demonstrators to be vigilant and report any actions that may seem out of the ordinary," the alert said. "If anyone notices something suspicious, please contact a nearby officer or call 9-1-1. A physical description, clothing description, and/or vehicle description is helpful. Also, please report any ‘out of the ordinary’ actions you have observed."
"The intelligence we have received has also been distributed through a number of social media channels. We urge everyone to take those messages seriously."
