Elkins police arrested a man who allegedly rigged a doorknob in his home so it would shock his wife.

Herbert Caldwell Junior, 44, was charged with installing a booby trap, domestic battery and terroristic threatening. Officers summoned to Caldwell's home found electric fencing of the type used for cattle installed so a bedroom doorknob would shock anyone who touched it.

Police said the trap was rigged to keep Caldwell's wife out of the bedroom. Investigators said the woman wasn't seriously injured by the shock.
