BOSTON — Two-time Oscar-winning actor Kevin Spacey has asked a federal judge to imprison a Boston-area woman convicted of sending him threatening electronic messages.

The Boston Herald reports Spacey says in a letter that the threats from 55-year-old Linda Louise Culkin of Quincy caused “eminent fear,” and asked that she remain in custody and “undertake intense psychiatric treatment.”

Culkin was scheduled to be sentenced Tuesday in Boston, but a judge sent her for a psychiatric evaluation. Culkin pleaded guilty in November to charges.
