Four people have been federally indicted in connection with clashes and threats against federal officers in Minneapolis following protests after an immigration officer shot Alex Pretti.

Claire Louise Feng, 27, of St. Paul, is accused of biting off the fingertip of a Homeland Security special agent during a January 24 protest and faces assault charges.

Brenna Marie Doyle, 18, of Spokane, Washington, along with James Patrick Lyons, 45, of California, and Jose Alberto Ramirez, 29, of Illinois, are charged with threatening FBI agents and their families, with communications allegedly sent via phone calls and text messages.

The threats arose after agents’ vehicles were vandalized during the protests and personal information was stolen and shared on social media, the AP has reported.

Attorneys for the defendants have said their clients will contest the charges or are awaiting evidence, and none of the four have entered pleas yet.
