Teacher sent sick death threat letters warning she will have 'throat slit like pig'

A teacher is living in fear after being subjected to - one of which warned she would have her throat slit "like a pig".

It was reportedly less explicit than the first letter that threatened to "slit her throat like a pig". The third letter has since been added to the investigation that is being carried out by the Libourne prosecutor's office.

A press release from the Libourne public prosecutor obtained by said: "Following a letter found Tuesday morning in a classroom at the Jean Monnet high school in Libourne targeting a teacher at the establishment, an investigation has been opened into the charges of death threats against a person responsible for a public service mission, committed on the grounds of race, ethnicity, nation or religion."

No suspects have been arrested over the multiple letters that have targeted the same teacher since last year. Police patrols have been set up around the school and have been "reinforced".

The Bordeaux education office condemned the threats. A spokesperson said: "The situation is being taken very seriously and is being monitored very closely."
