HOUSTON, Aug. 3 (Xinhua) -- A mass shooting on Saturday killed at least 20 and injured 26 others in the U.S. state of Texas, local officials said at a press conference.

The suspect, already taken into custody, was identified as a 21-year-old white male from Texas, according to Texas Police Chief Greg Allen.

The shooting has a "nexus to a hate crime," said Allen. Meanwhile, the Federal Bureau of Investigation cautioned that more investigative work is needed to determine the nature of the crime.

Allen said the state of Texas will lead the prosecution of the suspect, adding that the state is currently looking at potential capital murder charges.

The deceased will remain at the scene while the investigation continues, Allen said.
