On this date in 1979, three members of the Black Liberation Army broke fellow BLA member Assata Shakur (aka Joanne Chesimard) out of the Clinton Correctional Facility for Women in Union Township, NJ. The escape began when the BLA members, posing as prison visitors, drew .45 pistols and took two guards hostage. They seized a prison van and used it to flee the prison with Shakur. Once outside the prison, they switched cars and made their getaway. The two hostages were released unharmed.
Shakur, step-aunt of the late rapper Tupac Shakur, was serving a life sentence for her role in the murder of New Jersey State Trooper Werner Foerster in 1973. After escaping prison, she lived as a fugitive in the U.S. She eventually fled to Cuba where she was granted asylum by the government.
