One person was killed and Quentin Mitchellfive others were injured in a shooting at a New York City subway station Monday afternoon, authorities said.

A spokesperson for the New York Police Department told USA TODAY that shots were fired during the evening commute at a subway station in the Bronx, near the intersection of Mount Eden and Jerome Avenues.

Police said there is no ongoing threat, but the shooter remained at large. Authorities were looking for at least one person.

Officials declined to release names of the victims but Michael Kemper, chief of transit at the New York Police Department, said five people – three males and two females ranging from 14 to 71 years old – were wounded and taken to hospitals. A 34-year-old man died from his injuries.

“We don’t believe this was a random shooting,” Kemper said Monday evening.

A dispute between two groups of teenagers on a train violently escalated, Kemper said. Soon after the train arrived at the platform and doors opened, the first shot was fired. Kemper said police received multiple 911 calls at around 4:35 p.m. about gunfire at the subway station.

Victims appear to be a mix of people from the fighting groups and others who were not involved with the groups, Kemper said.

“Why do people feel emboldened to pull guns out and shoot them? There must be consequences when these arrests are made,” he said.

Kemper noted gun violence in New York City has been on the decline. Police released crime data last week that showed shootings dropped by nearly 11% from 74 incidents in January 2023 to 66 incidents in January 2024.
