A fourth teenager has been arrested in the death of a good Samaritan who was struck by a train while trying to help an assault victim on New Year’s Day in New York City, police said.

Noel Rosado, 19, was arrested Friday afternoon on recommended charges of murder, manslaughter, robbery, gang assault and assault in the incident that led to Roland Hueston’s death, the New York Police Department said.

CNN has contacted the Manhattan district attorney’s office to ask about Rosado’s charges. CNN’s attempts to reach legal representation for Rosado weren’t immediately successful.

Police said a group of people displayed a knife and assaulted a 38-year-old man on a platform at the Fordham Road subway station in the Bronx around 2:40 a.m. on January 1.

At some point, the man fell onto the roadbed where the tracks are as a train approached, according to police.

Hueston, 36, of the Bronx, tried to help the man from the tracks, but was “subsequently struck by the oncoming train, causing (Hueston’s) death,” police said in a news release.

The train didn’t strike the assault victim, who was eventually treated at a hospital for a broken arm and released, according to police.

The assailants fled the station. Police didn’t say how many people were involved in the attack, but in early January they released surveillance photos from the scene showing a group of people wanted in the assault.

Three other male teenagers, a 16-year-old and two 17-year-olds, were arrested in January in connection with the incident, according to NYPD. At the time, each was held on recommended charges including murder, robbery, gang assault and assault.

The subway station, located on 188th Street, falls under the 46th Precinct, which has seen 34 felonious assaults in the past 28 days, according to city data.

On January 15, a 40-year-old woman died after being pushed in front of an oncoming train in what police said was a random attack at the Times Square-42nd Street subway station. A suspect was charged with second-degree murder after he turned himself in less than an hour later, police said.

Eight days later, a 62-year-old man suffered minor injuries after being pushed onto subway tracks in Lower Manhattan, according to the NYPD. After that incident, the head of the city’s transit agency urged people to stay away from the edge of platforms.
