LINCOLN, Neb. (KSNB) - A former Osceola man with charges against him out of multiple Nebraska counties, including for a police shooting in Hastings last year, now has a new charge.

Anthony Mattison, 34, is charged with second degree assault in Lancaster County Court. Charges were filed just this month but the incident in question happened earlier this year.

According to court documents, the assault happened on February 4 at Nebraska Department of Correctional Services (NDCS) Reception and Treatment Center (RTC) in Lincoln.

In the complaint, it said Mattison “did unlawfully strike or wound” a staff member at the facility.

Back in February, NDCS sent out a release regarding an inmate assault on February 4 resulting in serious injury at the same facility where Mattison was being treated.

The release said the assault occurred when the staff member was escorting the inmate from a holding cell to the bathroom and back again. The inmate refused to return to the holding cell and punched the staff member in the face. The staff member was able to subdue the inmate until responding staff removed him from the area. The injured staff member was treated at the hospital for a broken nose.

Mattison is scheduled for an arraignment on June 7 at 2 p.m.

As for charges against him in Adams County, prosecutors are still waiting for the results of a second competency evaluation to see if Mattison is fit to stand trial for attempted murder in the officer-involved shooting.
