A teenager was arrested on Thursday in connection with a shooting at a Bronx subway station this week that killed one person and injured five others, the police said.

The teenager, Langel Jones, 16, was apprehended as he was leaving an apartment in the Highbridge neighborhood of the Bronx where he lives with his mother, said Joseph Kenny, the chief of detectives. He will be charged with murder, Chief Kenny said.

Obed Beltran-Sanchez, 35, a Mexican laborer who lived in the Bronx, was killed in the shooting. Five other people, whose ages ranged from 14 to 71, were injured, the police said.

The shooting took place during the afternoon rush hour on Monday at the Mount Eden Avenue subway station in the Bronx. It occurred after a fight broke out between two groups of teenagers on a northbound No. 4 train at 4:30 p.m.

Investigators believe that the shooting was in retaliation for another shooting last month, Chief Kenny said. In that shooting, on Jan. 15, the two groups were fighting in front of a bodega on Davidson Avenue in the Bronx when, the police and Chief Kenny said, one of the boys, 14, shot at his rivals, striking a 17-year-old in the leg.

On Monday, the 14-year-old was on the No. 4 train with his friends when they ran into their rivals, including Mr. Jones.
