April Sims was fired from her job at the Dallas Police Department for violating the department's social media policy, The Dallas Morning News reported.
Sims, who had been working as a 911 operator since November, posted a number of racist comments on her private Facebook page, such as "I can count on 1 hand the black people I know who don't have [expletive] for brains!!!"
She also compared black people to animals, saying: "Black people are outrageous! They are more like animals, they never know how to act ... Always causing problems."
Dallas City Council member Dwaine Caraway told WFAA-TV, Dallas/Fort Worth, Sims' comment "embarrasses not just the department, it embarrasses the city."
"No. 1, I am shocked and it saddens me to know that this is going on and still taking place in today's time, especially here in 911," Caraway said.
