An Arizona man has been sentenced to four years in prison for assaulting a federal officer.
Prosecutors say 39-year-old Jason David Grisham, of Tonelea, was sentenced by a U.S. District Court judge in Phoenix this week.
Grisham had previously pleaded guilty in the case.
Prosecutors say Grisham assaulted a Navajo Nation police officer in Kayenta last June.
The investigation in the case was conducted by the FBI and the Navajo Nation Department of Public Safety.
