A nurse in Indiana has lost her job after she was reportedly found to have written “several troubling posts” on social media, one of which claimed sons of white women should be “sacrificed to the wolves”.

The nurse, who worked for Indiana University Health in Indianapolis, tweeted under the name “Night Nurse”. Local reports have linked the account to a woman named Taiyesha Baker.

One tweet written by the nurse read: “Every white woman raises a detriment to society when they raise a son. Someone with the HIGHEST propensity to be a terrorist, rapist, racist, killer, and domestic violence all star. Historically every son you had should be sacrificed to the wolves B****”.

IU Health issued a statement to 13WHTR on Saturday, which said: “IU Health is aware of several troubling posts on social media which appear to be from a recently hired IU Health employee. Our HR department continues to investigate the situation and the authenticity of the posts.”

On Monday IU Health announced that the woman is “no longer an employee of IU Health”.

Racist and controversial comments made online that have caused workers to be suspended or fired have made headlines this year.

In September a volunteer firefighter in Ohio was suspended after allegedly writing on Facebook that he would rather save a dog than an African American, because “one dog is more important than a million n******”. He was suspended without pay pending a disciplinary hearing.

After the Charlottesville riots a Twitter account called “Yes, You’re Racist” began identifying white nationalists who had been photographed marching though the town.

Cole White, who was identified as one of the white nationalists, lost his job at the Top Dog restaurant chain in Berkeley, California, following the Charlottesville violence, the New York Post reported.
