DENVER — Officials say an inmate assaulted theater shooter James Holmes and a security officer at the Colorado State Penitentiary.

A jail spokesman said the inmate lunged at Holmes and took a few swings at him while the officer was escorting Holmes through a hallway on Oct. 8. Holmes was not injured. The inmate accused of attacking Holmes will be disciplined during a hearing inside the prison.

A judge in August sentenced Holmes to life in prison without parole for killing 12 people and wounding 70 others at a movie theater in suburban Denver in July 2012.
