A teenager was busted for robbing a 14-year-old boy at a Brooklyn subway station last month, police said.

Jonathan Garner, 17, was taken into custody Monday night for the Sept. 10 robbery at New Utrecht Avenue and 55th Street, police said.

Garner and two other teens allegedly approached the younger boy around 3 p.m. and demanded his phone. Garner punched the boy in the face, police said.

Garner is not related to Eric Garner, the Staten Island man who died while in police custody in July 2014, the NYPD said.
