Nathaniel Wallace, 38, and Rafael Washington, 35, were arrested Thursday. Both men are charged with one count of delivering and another count of possessing cocaine.
Arrests came during a drug bust in Country Club hills. Another suspect -- 37-year-old Nyarko Johnson -- was shot and killed by police during the incident. A fourth suspect remains in custody.
A squad car rolled over at the scene and four officers were injured. They were all treated and released.
