MIAMI BEACH (CBS4) – Singer Solange Knowles, little sis to newly pregnant pop-superstar Beyonce, has hired famous South Florida attorney Roy Black to represent her in a case involving the Miami Beach Police Department.

According to the R&B singer, she was the victim of discrimination after an officer allegedly pulled a weapon on her which has led to an internal affairs investigation.

According to police, Knowles was denied entrance to “Club Cameo” on South Beach Sunday night because she was carrying a five-foot tall inflatable banana. Police claim Knowles got angry and she claimed the reasons she wasn’t allowed in the club were racially motivated.

In a press release, Miami Beach Police Department spokesman Juan Sanchez stated officers who worked off-duty at the club escorted Knowles across the street to “further the conversation, where Ms. Knowles claimed one of the officers pulled a ‘weapon’ on her, not a firearm, and threatened to deflate the banana.”

The younger Knowles took to Twitter to express her anger over the incident, which she claimed was the result of “discrimination.”

“I have literally had my last leg with discriminating police! Miami police department will be notified,” she first tweeted. “A police officer just pulled a weapon on me…. I have done NOTHING illegal, against the law, or anything of the sort.”

Knowles’ public rant against the police lasted for nine tweets.

“I’m only tweeting this to raise awareness. I could have left quietly, but I am sick & tired of this scenario being played over & over again,” she wrote. “It is time to do something about it. I am a mother raising a young black child in America. I’m going to die trying!”

In her tweets, Knowles indicated that she had the name of the officer who pulled the weapon and would be filing a formal complaint.

Sanchez confirms Knowles contacted the Miami Beach PD regarding the incident and the Internal Affairs Unit will be contacting her regarding her allegations.

No other information about this incident will be released from Miami Beach PD, said Sanchez, due to the Internal Affairs Investigation.
