A Holland-based US professor and activist is accusing police in Belgium of abusing her as part of a crackdown on a recent protest for migrant rights. Dr. Marianne Maeckelbergh of Holland’s University of Leiden says she was taking pictures of the “No Border Camp” in Brussels when she was arrested. Maeckelbergh says Belgian police dragged her by her hair, chained her to a radiator, kicked her, and subjected her to verbal abuse as well as threats of sexual assault.
