WHITTIER (CBSLA.com) — A former teacher at a Catholic school in Whittier claims students could be in danger because of a man who is allegedly stalking the principal.

The first grade instructor, who recently resigned from St. Bruno Catholic School, sent a mass email to parents about a supposed deranged suspect who has threatened the principal for a number of years.

“The principal has had a deranged man stalking her for many years and has followed her to St. Bruno School,” the teacher wrote in an email. “He has left packages on the fronts steps, been in the parish center, called the school on numerous occasions and sent things to the school through the mail. Two of his latest communications have mentioned death.”

The teacher also revealed that every staff member was given pictures of the alleged perpetrator, as well as a description of his car.

The school is scheduled to have a meeting with parents, the Archdiocese of Los Angeles and other community members to discuss the teacher’s revelations on Tuesday.

Calls to St. Bruno, the principal and the teacher who sent the email were not returned.

Whittier police detectives would not confirm any information about the reported stalker.
