A Chicago teen is taking local police to court for $100 million after she claims that excessive force during a racially charged arrest caused her to lose her unborn child.

Candice Williams, a former student at Crete-Monee High School, says a racist security guard at the school called the police on her after her track practice.

According to court papers filed Tuesday, the security guard called the girl the "n-word" and is accused of showing a black co-worker a paper replica of a Ku Klux Klan mask, saying it would "scare the bi**h.”

In April of 2008 Williams says the security guard called police because she did not want to wait outside for her ride even though she told her she was pregnant and anemic.

When officers arrived, they slammed the girl into the wall and then held her down on the ground with a knee in her back.

When she later visited the hospital her 9-week-old fetus did not have a heartbeat.

She is seeking $50 million in compensatory damages and $50 million in punitive damages.
