A white couple pointed guns at protesters in St Louis, Missouri, as a group marched toward the mayor’s home to demand her resignation.
A social media video showed the unidentified armed couple standing outside their home on Sunday evening in the Central West End neighbourhood shouting at protesters, while people in the march moved the crowd forward, urging participants to ignore them.
It was not immediately clear whether St Louis police were aware of the incident. An email and phone call from the Associated Press to police were not immediately answered.
The group of at least 500 people were heading towards the home of the mayor, Lyda Krewson, chanting, “Resign Lyda, take the cops with you,” news outlets reported.
Resignation demands come after a Friday Facebook live briefing, where Krewson read the names and addresses of several residents who wrote letters to the mayor suggesting she defund the police department.
The video was removed from Facebook and Krewson apologised on Friday, stating she did not “intend to cause distress”.
The names and letters are considered public records but Krewson’s actions received a heavy backlash.
An online petition calling for her resignation had more than 43,000 signatures by Monday morning.
“As a leader, you don’t do stuff like that … it’s only right that we visit her at her home,” said state representative Rasheen Aldridge, speaking into a megaphone at the protest on Sunday.
