A 13th suspect has been arrested in the murder of Bronx teen Lesandro “Junior” Guzman-Feliz, who was hacked to death by a machete-wielding gang after being dragged from a Bronx bodega, police said.

Ronald Urena, 29, is accused of taking part in the June 20 attack that left Guzman-Feliz, 15, dead in a case of mistaken identity, cops said.

Urena was charged with murder, manslaughter, gang assault, criminal possession of a weapon and conspiracy. He is the oldest in the group, along with another 29-year-old man, Diego Suero.

Suero is the alleged leader of the notorious Trinitarios gang, which planned and carried out the attack.

Urena remained in custody on Sunday night.

A 12th suspect in the caught-on-video murder had been picked up in Connecticut last month.

Guzman-Feliz was honored last week during a ceremony for those who graduated from the Law Enforcement Exploring Academy, of which he was a member.

“We have to make a change, stop the violence . . . make a difference in the world,” Guzman-Feliz’s mom, Leandra Feliz, said at the time.
