Aaron Hernandez

A Bristol County grand jury handed up an indictment Thursday charging former New England Patriots player Aaron Hernandez in an alleged jailhouse assault.

Hernandez is accused of assaulting another inmate at the Bristol County House of Corrections in Dartmouth on Feb. 25. He's also accused of making a threat inside the jail last year.

The indictment charges Hernandez with assault and battery and threats to do bodily harm. An arraignment date was not immediately set.

Hernandez is being held at the House of Corrections while he waits for his trial on a murder charge in the killing of Odin Lloyd.
