(Reuters) - The American Civil Liberties Union has accused Minnesota law enforcement of wrongly arresting, injuring and harassing journalists covering unrest sparked by the death of George Floyd, an unarmed black man, in Minneapolis police custody.

District Court in Minnesota on Wednesday, the ACLU accuses the Minneapolis Police Department and Minnesota State Patrol of shooting journalists in the face with rubber bullets, arresting reporters and photographers without cause, and threatening them at gunpoint.

A Minnesota State Patrol spokesman said the agency could not discuss the specifics of the litigation, but said it can be difficult to distinguish between journalists covering a protest and people who violate curfews or refuse to leave the area.

“While not all of the incidents involve the Minnesota State Patrol, we are reviewing the incidents involving our troopers in an effort to prevent similar incidents in the future,” the spokesman, Bruce Gordon, said in an email.

The suit alleges a Minnesota State Patrol officer “forced WCCO videographer Tom Aviles to the ground and arrested him even though Aviles had identified himself as a member of the press and was carrying a large video camera.”.
