The suspect, a 20-year-old Orthodox man, showed up at the 61st Precinct with his attorney Tuesday — a day after the NYPD released an enhanced photo of him as a suspect in the crime.
But when investigators contacted the victim after the suspect came forward the family "stopped cooperating with the cops," a police source said.
The suspect's father is the principal of a yeshiva and his grandfather is an "influential rabbi," the source said.
The victim was with her mother when the suspect — initially described as a white or Hispanic man — approached her on E. 7th St. in Midwood about 4:30 p.m. Feb. 16.
"Come here," the man demanded of the teen.
When the girl refused, he grabbed her by the shoulder and wouldn't let go until the victim's former teacher intervened, officials said.
"The case and the investigation is closed," an NYPD spokesman said Wednesday. "No one is charged."
Detectives made their decision after conferring with the Brooklyn District Attorney's office, the spokesman said.
