Other teen knifed 2 weeks before machete attack

A group of suspected Trinitarios gang members slashed a young man's head in the Bronx – two weeks before teens from the same Dominican street gang butchered a 15-year-old boy to death, police said Sunday.

The teen suspects, all between 14 and 18, approached the 17-year-old victim on E. 196th St. near Jerome Ave. in Fordham Manor around 8:30 a.m. on June 8., cops said.

They slashed him in the head with a knife and punched him repeatedly before running off, police said.

The victim was treated for a cut to the head at a nearby hospital.

Cops released surveillance video Sunday showing at least three suspects fleeing the scene.

It's unknown if they belong to the Trinitarios gang — whose members allegedly murdered Lesandro (Junior) Guzman-Feliz with a machete in a case of mistaken identity outside the Cruz and Chiky Grocery in the Bronx on June 20 — police said.
