A New York City private high school teacher has been fired after making an anti-police tweet.
Laura Lynne Duffy, a math teacher at Fontbonne Hall in Brooklyn, tweeted that she was going to "intentionally" dress-up during the student-led "dress down" fundraiser on Wednesday in support of two New York City police officers who were killed while responding to a domestic violence call in January.
"If anyone was wondering, I am intentionally dressing up today. #Abolition #BLM," Duffy said in a now-deleted tweet.
The Sisters of St. Joseph, Brentwood, New York, which supports Fontbonne Hall, posted an update to Facebook stating that as of Friday, Duffy is no longer employed at the school.

"The Sisters of Saint Joseph support the Administration of Fontbonne Hall Academy School which has determined that Laura Lynn Duffy is no longer in the employ of FHA effective Friday February 4, 2022," the Facebook post said.
Mary Ann Spicijaric, the principal of Fontbonne Hall confirmed to Fox News Digital that Duffy is no longer employed at the school effective Friday.
On Wednesday, the school issued a statement on Twitter calling Duffy's tweet "politically charged" and said that it does not endorse the comment, adding that the school is conducting an internal investigation.

The fundraiser was held in support of New York City police officers Jason Rivera and Wilbert Mora, who were shot and killed while responding to a domestic violence call on Jan. 21.
