Trae Tha Truth Shot

(CNN) -- Three people were killed early Wednesday in a shooting at a Houston strip club that injured area rapper Trae Tha Truth.

The dead include two men and a woman, but police have not released their names. A fifth person was also wounded, police said.

No arrests have been made or suspects named, but investigators are looking at the possibility that the attack is related to a domestic dispute or an earlier shooting at the club, Houston Police spokesman Victor Senties told CNN.

Trae Tha Truth, whose real name is Frazier Thompson, was treated for a minor gunshot wound and released from Houston's Memorial Hermann Southwest Hospital, a hospital spokesman said.

Grand Hustle, his Atlanta-based record label, posted a message on its website Wednesday saying the rapper was "doing OK."
