A Charenton man pleaded guilty before U.S. District Court Judge Richard T. Haik today to assaulting a woman and Chitimacha tribal police officer.

David Frederick, 38, assaulted his girlfriend on Chitimacha tribal lands on Jan. 27. While being booked for the assault, he attacked a Chitimacha tribal police officer and attempted to take the officer's handgun. A second officer got involved, and Frederick was subdued with pepper spray and a TASER.

Frederick had previously assaulted his girlfriend at her residence on Jan. 25.

He faces 20 years in prison, a $250,000 fine and three years of supervised release for the officer's assault and a maximum penalty of six months in prison, a $250,000 fine and one year of supervised release for the assault of his girlfriend within tribal lands.

The U.S. Attorney's office prosecutes both felonies and misdemeanors on tribal lands when at least one involved party — either the victim or defendant — is Native American.

Assistant U.S. Attorney Daniel J. McCoy is prosecuting the case.
