Updated 6:19 p.m. ET July 16: CVS has fired two employees who called police when a black female customer attempted to use a coupon a manager believed to be fraudulent, Chicago Tribune reported.

"We have completed our investigation, and as a result, the two colleagues who were involved are no longer employed by CVS Health," Mike DeAngelis, CVS Health spokesman, said in an email.

Previous story: CVS has apologized to a black woman and is investigating an incident in which a white manager called police on her after she tried to use a coupon at a Chicago store on Friday.

Camilla Hudson, 53, who said her Facebook post detailing the incident was removed for unspecified reasons by the social media site, also shared video on Twitter of her interaction with the CVS manager who claimed she had forged a coupon.

Hudson said she shared her experience after other recent stories where police were called by white people because of minor or perceived infractions by black people.

"I was not yelling, I did not raise my voice, I did not use profanity, I did not call anyone outside of their name -- other than not accepting, basically, 'Screw you,' that was my offense, if you will," Hudson told Block Club Chicago. "As a woman, as a black woman, as a native Chicagoan, I'm just tired of it. I'm tired of it."

Police were called to the store for an assault in progress, according to Block Club Chicago. Hudson was told by police she had to leave or else it would be considered trespassing.

"They were not awful," Hudson told Block Club Chicago regarding the interaction with police. "I explained to them what had happened and how it had happened, and they said, 'When we get these calls we do have to respond … (but) you're going to have to leave,' and I said, 'Why do I have to leave? I'm a customer here.'"

CVS reached out to Hudson Saturday as her post went viral.

"Our Region Director in Chicago contacted Ms. Hudson as soon as we were made aware of this incident," CVS said in a statement, according to Block Club Chicago. "CVS has begun an investigation and we will take any corrective action that is warranted to prevent it from happening again. CVS Pharmacy does not tolerate any practices that discriminate against any customer and we are committed to maintaining a welcoming and diverse environment in our stores."
