NEW YORK — The Roman Catholic priest accused of stalking NBC talk-show host Conan O'Brien has pleaded guilty to disorderly conduct.

The Rev. David Ajemian admitted to the offense — sending letters and DVDs to O'Brien's home and business.

Ajemian was arrested in New York City last year while trying to enter a taping of O'Brien's show, despite being warned to stay away by NBC security personnel.

Prosecutors say Ajemian began sending letters to O'Brien in September 2006. He has been placed on leave by the Boston Archdiocese.

Ajemian and O'Brien attended Harvard University at the same time, but it's unclear whether the two crossed paths there
