A Ku Klux Klan recruiter failed to appear in court on assault charges Tuesday and a judge has issued a warrant for her arrest.

Donna Marie Upson, known as "Baby Hitler" among Klan members, faces charges of assaulting two prison workers while behind bars in Springhill, N.S.

Upson, 23, was serving 13 months for uttering threats against a black minister in Dartmouth, N.S.

She appeared in court in February and pleaded not guilty to the assault charges.
