Police say eight people have been shot after rival gangs confronted each other during a Dallas nightclub's rap competition, and at least one person is critically injured.

Dallas police say the incident started around 2:30 a.m. Saturday at the Rolls Royce club when members of one gang pulled guns and began firing.

Police spokeswoman Melinda Gutierrez says conditions of the victims range from fair to critical. She didn't have additional information. No arrests have been made.

Online police reports allege that a 22-year-old man was about to take the stage when he began arguing with a man, who shot the 22-year-old three times before firing into the crowd.

The reports say a 23-year-old man shot in both legs was in critical condition but able to tell officers about the suspects.
