The 32-year-old Koppenhaver is accused of beating Christy Mack so badly early Aug. 8 that she feared for her life and ran naked from her house to seek help from neighbors.

Koppenhaver is due for an extradition hearing in on a fugitive warrant issued after Las Vegas authorities accused him of multiple felony battery, lewdness and coercion charges.

The U.S. Marshal’s Service and officers from Simi Valley police arrested Koppenhaver about 1:45 p.m. Friday at the Extended Stay America Hotel at 2498 Stearns Street, the Associated Press reported.
