An alarming video making the rounds on social media shows the moment an argument between members of two notorious street gangs’ spirals out of control on a Queens subway platform.

Police say the man who fired the gun Sunday is a 26-year-old member of MS-13, the vicious gang with roots in Central America.

The victim is 20-year-old Abel Mosso, allegedly a member of the rival 18th Street gang, a violent group of mainly Mexican and Central American immigrants known to frequent Roosevelt Avenue in Queens.


“Approximately 5 or six shots are fired during that incident, striking that victim multiple times,” said Chief of Detectives Dermot Shea.

Sources say the gun belonged to Mosso, and the suspect wrestled it away from him.

Police sources identified the killer as Ramiro Gutierrez, and said detectives picked him up Monday morning.

He has 12 prior arrests, and was out on $2,500 bail on charges he planned to burglarize a home in Kew Gardens and beat two people with a pipe.

The NYPD has long said MS13 isn't a big problem in the city but the killing was at least the third allegedly committed here by the gang since 2017.

Subway crime ticked up 3.8 percent last year. But the head of New York City Transit, Andy Byford, visited the station at 90th St. and Elmhurst Avenue, where the killing occurred, trying to reassure riders. He issued a statement calling the subway "remarkably safe," a message reinforced by the NYPD's chief of detectives.

“Whether you're in 1980, 1990 and or 2019, to have an incident like this is troubling,” said Shea. “When you look at crime in transit, on trains, in stations, it's at a near-record low. Crime this year in transit is down. To have that conversation and then to have an incident like yesterday is not easy. The subways are safe."
