A Dallas police lieutenant has been suspended for posting a video of herself online performing a rap song that contains profanities and threats of violence.
    
Police officials said Lt. Regina Smith, performing as Lucille Baller, "brought discredit to the department."
    
Smith was placed on administrative leave in November but her disciplinary hearing wasn't held until Friday. Assistant Police Chief Cynthia Villarreal issued a five-day suspension.
    
Officials said that as owner of the Big Rush In music production company, Smith appeared in uniform on the company website. In one video she displays her service weapon while holding a bullet and "making inappropriate statements."
    
Smith is assigned to the property crimes division.
    
Her attorney, Chris Livingston, said she's served the department with distinction for 25 years.
