On Monday, protesters commemorating the anniversary of the Michael Brown shooting shut down Interstate 70 during rush hour, forming a human chain across the roadway. Undeterred, a woman in an SUV pushed her car through the crowd, knocking protesters aside.

Now, charges have been filed, but not against the driver—against two of the protesters.

Brittany Ferrell, 26, and Alexis Templeton, 21, prominent protesters who founded the group Millennial Activists United, were arrested yesterday in Clayton. Ferrell has been charged with first-degree property damage, first-degree trespass, and peace disturbance. Templeton has been charged with third-degree assault, first-degree trespass, and peace disturbance.

“The charges stem from the efforts of the defendants to block traffic on Interstate 70," says County Prosecutor Bob McCulloch. "Templeton is accused of punching the victim as our victim attempted to drive past the defendant. The victim suffered an eye injury as a result. Ferrell kicked the victim’s car as she passed causing nearly $5000.00 in damage.”

In a previous statement to news media, a county police spokesman said the driver sustained a "sucker punch" from the protesters.

On Wednesday, the hashtags #Free Alexis and #FreeBrit were trending on Twitter as fellow protesters petitioned for the couple's release.

Ferrell and Templeton, in addition to being prominent voices in the #BlackLivesMatter movement, also made headlines last December when they wed at City Hall, following a ruling legalizing same-sex marriage in the city. The couple met last August while protesting Brown's death.
