HUMBOLDT, TN — One person was killed and another was critically injured during a shooting that broke out during a high school basketball game in Humboldt, Tennessee, Tuesday night. 

Memphis NBC affiliate WMC-TV reports that the shooting happened in the lobby of the Humboldt High School gym. Students were gathered at the school for a basketball game against Northside High School. Police, sheriff's deputies and emergency medical personnel responded to the scene, the Jackson Sun reports. 

WMC-TV reports that the person who was injured was flown to a Memphis hospital for treatment. Law enforcement officials have not yet released the names of the two people shot in the incident. Providing the Jackson Sun with an update about the incident, Humboldt Police Chief Reynard Buchanan Sr. later said others were also apparently injured in the incident. He said those people "showed up at nearby medical facilities," but that "none of those injuries were life threatening." 

In a news release published via social media Tuesday night, Humboldt City Schools says the shooting was a result of an altercation between two adults. No students were involved, and no students were injured, the school district says.

The school district said Tuesday night that authorities were still working to apprehend the suspect. But, the Humboldt Police Department later announced a suspect was in custody. "He's not charged with anything," Buchanan told the Jackson Sun. "But he's in custody for investigative purposes."

In its news release, school district said it has cancelled all classes and before and after school activities for Wednesday. 

Humboldt is in Gibson and Madison counties in northwest Tennessee. The high school is in Gibson County. It's about an hour's drive south of Union City.
