FERGUSON, Mo. (AP) — More than a dozen protesters remain in custody after being arrested during Thursday’s protests in Ferguson, and some local officials and rights groups are questioning if police overreached.

Authorities said Friday that 13 people were arrested for failure to comply with police, noise ordinance violations and resisting arrest.

Patricia Bynes, a Democratic committeewoman from the Ferguson area who was there during the protesting, said protesters were warned against violence-inciting language. But she didn’t know what the demonstrators said.

The protesters were taken to a jail in neighboring St. Ann, and some were placed on a 24-hour hold. The American Civil Liberties Union says it is investigating the arrests.

Hundreds of people have been arrested during nearly two months of protests in Ferguson, including journalists and clergy members.
