NEW ROCHELLE - A group of parents at a New Rochelle Catholic school are accusing a teacher of making threats about the school on her personal blog.

The group, calling itself Concerned Iona Prep Parents, sent a letter to News 12, complaining about teacher Kristen Brescia. The parents say Brescia has bipolar disorder and has written threatening messages about shooting up the school on her personal blog, along with posts containing graphic sexual content. Brescia's blog also allegedly contains references to celebrities' children who attend Iona Prep.

Brescia, who's taught at Iona Prep for three years, is allegedly no longer in the classroom.

Iona Prep refused to discuss the matter with News 12, saying it's a personnel issue. New Rochelle police say they are not investigating Brescia or any reported threat.
