New York police on Tuesday were still hunting for the gunman who fatally shot another rider in apparently random subway shooting, the latest attack to spark worries over the safety of the city’s trains.

The fatal shooting inside a Manhattan-bound Q train on Sunday left one man dead in what police said was an attack “without provocation.”

Police Commissioner Keechant Sewell on Monday shared photos of an unidentified man wanted in connection with the shooting, saying, “We need all eyes on this,” as the search for the gunman continues.

The New York City Police Department said Tuesday the investigation was ongoing with no updates after the photos were released Monday morning.

The shooting comes as Mayor Eric Adams has sought to balance encouraging riders back into a system still recovering from the COVID-19 pandemic and promising safety after other violent attacks on the trains, including the mass shooting last month on a Brooklyn subway car.

“When you have an incident like this, it sends a chilling impact. There’s no getting around that,” Adams said Monday.

Crime in the New York transit system is up 62.5% so far this year, according to the latest statistics from the New York City Police Department, but is on par with crime levels from years before the pandemic, with last year seeing a sharp dip in transit crime by this time.

Before Sunday’s shooting, there had been at least three murders in the transit system so far this year, compared to four at this time last year. The number of grand larcenies, felony assaults and robberies is up, according to police statistics.

Ridership, however, remains around 60% of its pre-pandemic levels, according to data from the Metropolitan Transportation Authority, with 3 to 3.6 million riders on a given weekday recently.

Adams on Monday repeated his overture for riders to return to the subway: “The call is to come back to work. And the subway system being safe is a major driver to doing that.”

There was no police officer in the car where the shooting occurred Sunday, Adams added.

In February, Adams released a safety plan that aims to surge more officers into the system and connect homeless riders with city services. The plan came a month after the death of Michelle Alyssa Go, who was shoved onto the tracks at the Times Square station.
