Dozens of shots rang out outside a strip club in the Texas city of Houston on early Wednesday morning, leaving three people dead and a popular local rapper injured, police said. No arrests were made as of Thursday.

The incident happened at around 3:30 a.m. local time when more than 20 shots were fired in the parking lot of a strip club in southwest Houston. Hundreds of people were in the parking lot at the time of the shooting, but it was not immediately clear if only one person was responsible or if there were multiple shooters.

Houston Police Department spokesman Victor Senties confirmed three people were killed, including a woman and two men, but their identities were not immediately released. There are no suspects, but investigators believe the incident could be connected to an unspecified domestic dispute on Father's Day or an unspecified shooting in November 2011.

The female victim is believed to be an innocent bystander, although police did not disclose what led them to believe that.

Among the four people who were injured is popular local rapper Trae Tha Truth, whose real name is Frazier Thompson III, who was giving a concert at Diamonds Gentleman's Club that evening. He was taken by paramedics to Ben Taub General Hospital after being shot in the shoulder, but his condition was not life-threatening.
