New Jersey Attorney General Gurbir Grewal says that a fourth male prison guard has been charged with misconduct and tampering with records stemming from an attack on female inmates.

Grewal said in a statement Tuesday that Sgt. Matthew Faschan has been suspended and faces two counts of second-degree official misconduct and one count of third-degree tampering with public records or information.

The charges stem from an incident at the Edna Mahan Correctional Facility for Women, New Jersey’s only women’s prison, on Jan. 11. Three other guards are already facing charges.

Authorities say that at least six inmates at the correctional facility reported being assaulted by correctional police officers during a forced cell extraction.

State lawmakers have called for Gov. Phil Murphy to remove Department of Corrections Commissioner Marcus Hicks following the incident.

The state Senate passed a bipartisan resolution 35-0 earlier this month calling on Hicks to resign or be removed from his post.
