Six of the eight men suspected of taking part in the gang-related stabbing death of a Belmont teen arrived at the NYPD's 48th Precinct around noon Wednesday after their extradition from New Jersey.

As News 12 has reported, police arrested six suspects in Paterson, New Jersey. Four of them are Bronx residents: Jose Tavarez, 21, Manuel Rivera, 18, Danel Fernandez, 21, and Antonio Hernandez Santiago, 24. Jose Muniz, 21, is from New Jersey, and Jonaiki Martinez-Estrella, 24, is from Freeport, on Long Island.

Martinez is accused of delivering a fatal gash to the victim's throat.

The NYPD also arrested two other suspects in the city: 19-year-old Kevin Alvarez, and 23-year-old Elvin Garcia. All eight of them face a slew of charges that include murder.

They are all accused of taking part in the brutal slaying of Lesandro Guzman-Feliz, a member of the NYPD Explorers youth program who went by the name Junior.

Graphic surveillance video of the attack has circulated widely on social media and prompted massive public condemnation. The video ends with the blood-covered victim stumbling toward St. Barnabas Hospital -- which is a block away from the crime scene. Police say he died outside the door.

Sources say the men may have mistaken Junior for someone else before killing him, but police have not officially confirmed that information.

Police say a flurry of tips helped them arrest the eight suspects.

At least some of them have alleged ties to the violent Trinitarios street gang -- which may also be responsible for the unrelated stabbing of a 14-year-old boy on the Bronx River Parkway last week.

It's unclear if police will make more arrests in the case. The six latest arraignments came on the same day as the victim's funeral.

Each man has pleaded not guilty -- and the judge ordered each held without bail.
