WJZ reports that authorities were called around 9:35 p.m. requesting medical assistance for Darden, who was transported to a nearby hospital. She is said to have sustained superficial wounds which didn't require stitches or surgery.
Gray died back in April from severe spinal injuries while in police custody, sparking public outcry for justice not only in Baltimore, but around the country. His death was later ruled a homicide and six officers have been charged. Baltimore awarded his family $6.4 million in a civil settlement.
Darden is currently under psychiatric evaluation.
