Police are questioning a person that they believe is responsible for the  shooting death of a 14-year-old girl while she was riding home from a Sweet 16 party on a Queens bus, Police Commissioner Raymond Kelly said.

D’aja Robinson was struck and killed by a bullet while sitting on a Q6 bus Saturday around 8 p.m. in the South Jamaica neighborhood.

The suspect– who is 16, according to a law-enforcement official–was taken into custody without incident Thursday morning in the murder of D’aja, which unnerved a section of Queens that had been experiencing a reduction in crime. The official said the crime is believed to be gang related and D’aja was not the intended target.
