Des Moines, Iowa – A class action lawsuit has been filed against dozens of law enforcement officers over their actions toward protesters during a racial justice demonstration in Des Moines in May.

The lawsuit was filed last week by Gina Messamer, a Des Moines attorney already representing at least three individuals in cases stemming from protests over the death of George Floyd while he was in the custody of Minneapolis police. The lawsuit seeks to represent anyone arrested or assaulted by Des Moines officers in the early morning hours of May 31, The Des Moines Register reported.

Defendants in the lawsuit include 16 police officers, primarily from the Des Moines Police Department, another 60 unknown officers, Des Moines Police Chief Dana Wingert and the city.

“By illegally arresting, assaulting, and seizing the property of citizens in the downtown area, (police officers) intended to punish citizens for their protest activity – an exercise of their First Amendment rights – and to deter future demonstrations,” the lawsuit claims.

Police referred questions to the city’s legal representatives, who did not return messages seeking comment.
