Former New England Patriot Aaron Hernandez was indicted Thursday on charges related to a jailhouse fight, according to the district attorney's office in Massachusetts.

On Thursday afternoon, a grand jury in Bristol County indicted Hernandez, 24, on charges of assault and battery stemming from the jailhouse altercation on Feb. 25, according to CNN.

The former NFL star was also indicted Thursday for threatening to do physical harm to someone who worked at the jail in November.

The date for Hernandez's arraignment has not yet been set.

Hernandez's attorney did not immediately respond to CNN about the indictment.

While Hernandez is accused of punching an inmate in the face, neither man was seriously injured in the Feb. 25 altercation.

Bristol County Sheriff Thomas Hodgson said that jail officials will investigate how the two inmates came into contact because "no more than one inmate is supposed to be out at a time" in Hernandez's unit.

Hernandez is in Bristol County Jail awaiting a first-degree murder charge, for which he has pleaded not guilty.

Hernandez allegedly picked up Odin Lloyd from his apartment in Boston in a rental car shortly before Lloyd was found fatally shot on June 17.

Lloyd was found dead in an industrial park near Hernandez's North Attleborough home.

According to authorities, surveillance cameras show the rental car leaving the scene of the crime, and Hernandez carrying a gun when he returned to his home shortly after.

Hernandez has also been connected to a double shooting outside of a club in Boston's South End in 2012 and to a shooting that occurred in Miami last year.

Hernandez's associate, Alexander Bradley, claims that he lost an eye when Hernandez shot him in Miami. Bradley is also connected to the 2012 double shooting.
