Boston ? The Roman Catholic priest accused of stalking talk show host Conan O’Brien was admitted to a hospital for evaluation Saturday after briefly going missing.

The Rev. David Ajemian was reported missing by his father about 3:15 p.m. after he had not been seen for nearly three hours, police said in a statement. Police were told that Ajemian’s “mental health may be of concern.”

He returned to his parents’ home in Boston about 7 p.m. and voluntarily went to a hospital, police said.

Ajemian, 46, was arrested in New York City while trying to enter a taping of “Late Night with Conan O’Brien” despite being warned to stay away by NBC security personnel, prosecutors said Wednesday.

He is charged with aggravated stalking and harassment. A judge Friday found him fit to stand trial despite a psychological condition.
