Activists and protesters, including noted academic Cornel West, were reportedly arrested at the federal courthouse in St. Louis on Monday, as St. Louis County officials issued a state of emergency following a night of unrest in Ferguson.

The series of arrests came following a night in which a man who allegedly shot at police during a protest to mark the anniversary of Michael Brown’s death was himself shot and is now in critical condition.

The reports of the arrests trickled out on Twitter, where reporters and activists were broadcasting photos and streaming videos of the protest.

Among those also taken into custody were DeRay Mckesson and Johnetta Elzie, two prominent activists who were profiled by the New York Times Magazine earlier this year.

Elzie, who has more than 50,000 followers, sent out this tweet shortly before being taken into custody, an apparent reference to Sandra Bland’s mysterious death while in police custody last month.

As the arrests were going on, St. Louis County Executive Steve Stenger issued a state of emergency for the county, saying that “recent acts of violence would not be tolerated.” According to the order, St. Louis County Police Chief Jon Belmar was given command over “police emergency management” in Ferguson and “surrounding areas.”

Tyrone Harris, the man who was in critical condition after the alleged firefight with police, was charged with multiple crimes while in his hospital bed Monday, including first-degree assault on law enforcement.
