Who Is Callejero Fino, the RKT Singer Arrested With an Unregistered Gun and an Unlicensed Truck

Simón Natanael Alvarenga, better known as Callejero Fino, was detained while carrying a Glock .40 handgun that he allegedly had no permit to carry. Police said the weapon, classified as a weapon of war, had its serial number removed and contained 12 bullets in its magazine. He was also driving a truck without license plates.

The arrest has put renewed attention on the artist’s unusual path to prominence. Callejero Fino is one of the leading figures in RKT, a style that blends the rhythmic roots of cumbia villera with trap, reggaetón and música turra. Born in Buenos Aires on Feb. 7, 1995, he became known for bringing the experiences of working-class neighborhoods to major stages across Argentina.

Raised in Presidente Derqui, in Pilar district, Alvarenga first encountered neighborhood rap formally at 13. Without internet access at home, he went to local cybercafés to listen to artists such as Eminem and Tupac Shakur. He later competed in street freestyle battles, including the Halabalusa gatherings in Claypole, where he adopted the name Callejero Fino. The name combined his neighborhood identity with the polished lyrical style he wanted to project.

His earlier legal troubles led to house arrest with an electronic monitoring bracelet. During that period, rather than abandoning music, he organized daily livestreams from his home patio and held small festivals there. Visitors were asked to bring nonperishable food for community kitchens, helping his name spread and building a loyal audience. His commercial breakthrough came with the growth of RKT, including releases such as “Saka volvió el nene” from 2021 onward. His collaborations with Rei on “Tu Turrito” and with Emi on “En la intimidad,” as well as work with L-Gante, Emilia Mernes and La Joaqui, helped make him a major streaming success.
