ST. LOUIS (AP) – A $20 million federal lawsuit filed on behalf of four people arrested during protests following the death of Michael Brown accuses the city of Ferguson and its attorneys of constitutional violations and malicious prosecution.

The lawsuit was filed Tuesday, on the two-year anniversary of Brown’s fatal shooting by an officer. It names the city of Ferguson, prosecutors Stephanie Karr and Patrick Chaissang, and multiple city police officers.
The plaintiffs were acquitted of wrongdoing earlier this year.

The lawsuit claims the St. Louis suburb spent more than $120,000 in prosecuting cases against protesters who took to the streets in 2014 following Brown’s death. A Ferguson spokesman says the city has not reviewed the lawsuit and declined comment.
The suit was filed by the law firm Dowd & Dowd and the nonprofit Arch City Defenders.
