CLAYTON, Mo. (AP) — A cleric arrested during a protest in Ferguson has been found not guilty of willfully disobeying a police order to disperse.

A St. Louis County jury deliberated just 20 minutes Tuesday before ruling in favor of the Rev. Osagyefo Sekou.

The St. Louis native is scholar in residence at the Martin Luther King Jr. Research and Education Institute at Stanford University.

He was praying when he was arrested outside Ferguson Police headquarters on Sept. 30, 2014.

Sekou was among those who protested in the weeks after 18-year-old Michael Brown, who was black and unarmed, was fatally shot by white officer Darren Wilson on Aug. 9, 2014. A grand jury and the Justice Department declined to prosecute Wilson, who resigned in November 2014.
