All six are scheduled for an extradition hearing in New Jersey on June 26.
The New York Post, citing police sources, identified one of the suspects as Kevin J. Alvarez, 19.
One of the alleged killers who dragged a teenage boy from a Bronx bodega and hacked him to death on the street was nabbed because of his baggy trousers.
Prosecutors said the New Jersey house where authorities arrested the other six suspects is known as a hangout for a street gang called the Trinitarios.
Minnows Iceland fall short of World Cup shock against Croatia
But Iceland got one back on a penalty kick in the 76th minute, as Croatia conceded for the first time in Russian Federation 2018. Ivan Perisic has scored three World Cup goals for Croatia - only Davor Suker (6) has scored more.
Only one of the suspects could speak without the aid of a Spanish translator. Mourners filled the streets in the Bronx Monday, frustrated with the violence that cost 15-year-old Lesandro Guzman-Feliz his life.
The murderers may have been seeking revenge on a similar-looking youth, for making a raunchy sex video featuring one of the gangster's relatives - but attacked Guzman-Feliz instead. Collado-Feliz described her younger brother as a "good kid" who enjoyed playing video games like Fortnite and 2K "live every 15-year-old", she said.
Guzman-Feliz's family has called on members of their community to boycott the bodega where the attack took place, since they think that the owners could have intervened. The NYPD says they have received a "torrent of tips", so many they had to add extra staff to the CrimeStoppers tip line.
Danemark : Pione Sisto et Martin Braithwaite débutent contre la France
A l'entendre, l'équipe de France n'avait " rien de spécial " et Paul Pogba ne penserait qu'à sa coupe de cheveux. Même le gardien et capitaine Hugo Lloris devrait souffler un peu au profit du Marseillais Steve Mandanda .
Council members Ritchie Torres, Vanessa Gibson and Rafael Salamanca, who all represent parts of the Bronx, demanded the bodega's closure in a Monday letter to the Department of Consumer Affairs.
His death was among "the most brutal crimes" NYPD Chief of Patrol Terence Monahan has seen in his 36-year career. National Basketball Association star Carmelo Anthony and his wife, actress Lala Anthony, visited Guzman-Feliz's mother, Leandra Feliz, in her Bronx apartment and stopped by the teen's vigil set up outside the bodega where he was killed.
De Blasio called the killing a "disgusting frightful incident" and said "everyone responsible will be brought to justice".
Guzman-Feliz was in the NYPD Explorers program and had wanted to become a New York City police officer when he got older.
