A suspect was arrested in connection with a train shooting in Dallas that killed one person and injured two other people, officials said Monday.

The shooting happened about 4:30 p.m. Sunday when two people got into an argument aboard a northbound Green Line train near Hatcher Station, Dallas Area Rapid Transit Assistant Vice President Gordon Shattles said in a statement.

Two people, including a bystander, were shot and rushed to Baylor University Medical Center in Dallas, where one of those victims died, according to the transit system, known as DART. A third person was treated at the scene for a non-life-threatening injury.

“DART Police have apprehended the suspect and recovered the weapon used in the incident,” Shattles said. The suspect, whose name was not immediately disclosed, has been charged with one count of murder and two counts of aggravated assault with a deadly weapon.

Hatcher Station is about 30 miles south of Allen Premium Outlets, just north of Dallas, where eight people were shot and killed Saturday afternoon before police killed the gunman.
