While visiting with his dad in April's apartment, he stole some money from her wallet. Later, he was seen cuffed and taken away by two NYPD officers during April's report. He may have tipped the Foot off that she'll be in the subway. This also gave NYPD Chief Sterns the leverage over Danny's father, Charles, to keep April from butting into his duties under the threat of putting Danny in Juvenile Hall or Riker's Island Penitentiary if April did not leave Sterns alone.
