The Charlottesville Police Department is investigating a possible assault on one of its officers Saturday evening at the Downtown Mall, according to a press release issued Sunday night. The release alleges the officer and a masked man came into contact and fell to the ground. Several demonstrators — who were marching downtown from Grounds — proceeded to surround the officer and man on the ground, the release says. Shortly thereafter, the release says law enforcement officials separated the group and the demonstrators rejoined the march. The officer was not injured, and no injuries were reported for either the masked man or the demonstrators who intervened. Charges related to the incident remain pending.
