Four Grand Rapids police officers were exposed to an unknown chemical substance Friday as they attempted to make an arrest.
Officers stopped a vehicle in a parking lot of a gas station around 8 p.m. at the intersection of Burton Street and Kalamazoo Avenue in Grand Rapids, police said.
Police said when officers approached the vehicle, the driver pitched a bag of an unknown substance out of the window. The bag burst and exposed officers to what they believed to be a narcotic, according to a GRPD spokesperson.
