Detectives are looking for another suspected gang member for questioning for a Bronx bodega slaying this past summer, police said Wednesday.

Frederick Then, 20, has connections to the Trinitarios gang, which carried out the brutal stabbing death of 15-year-old Lesandro “Junior” Guzman-Feliz, authorities said.

A police spokesman would only say that Then is “wanted for questioning” and declined to reveal what, if any, role he may have played in the slaying. Then is about 6-foot-1 and 150 pounds.

At least 14 people have been arrested for the murder that shocked New Yorkers. Security video showed attackers pulling the 15-year-old victim out of a bodega before he was stabbed to death in the streets.
