Prosecutors are charging a Brooklyn man with menacing as a hate crime after he allegedly accosted an off-duty Muslim NYPD officer and her teenage son on Saturday evening.

Police say Aml Elsokary, one of the few Muslim officers on the force to wear a hijab while on patrol, was dropping her 16-year-old son off near Ridge Boulevard and 67th Street at around 6 p.m. Saturday when a Bay Ridge resident named Christopher Nelson approached. Elsokary says that after she had parked her car, she found Nelson shoving her son, and when he saw her he yelled, "ISIS bitch! I will cut your throat! Go back to your country!"

Nelson then allegedly fled. Elsokary, a native New Yorker, said she did not identify herself as an officer and was unarmed.

Cops caught up to Nelson on Sunday, and he was held on $50,000 bail at his arraignment today. He is facing three misdemeanor charges, of harassment based on race, menacing, and acting in a manner injurious to a child, as well as a harassment violation and a felony count of menacing as a hate crime. The felony carries a maximum sentence of four years imprisonment, two of the misdemeanor counts carry a maximum of a year in jail, and the third carries a maximum of three months in jail.

Nelson's lawyer did not immediately respond to a call seeking comment.

Elsokary reportedly signed up to be a cop after the September 11th attacks, to "show people that the terrible acts of the day contradicted the teachings of Islam," as Mayor de Blasio put it at a 2014 Ramadan Iftar dinner at Gracie Mansion. The officer was lauded that year for rescuing a grandmother and her 1-year-old granddaughter from a fire on her beat in Williamsburg.

Nelson's neighbor Linda Rasport told CBS2 she was "very surprised" by his arrest, explaining, "I never saw that in him."

Once a Scandinavian enclave, Bay Ridge is now home to a mix of Italian and Irish Americans as well as Greek, Arab, Russian, and Chinese immigrants. The neighborhood is still 60 percent white non-Hispanic, according to recent Census data, but nearly 50 percent of residents speak a language other than English at home. According to the Arab American Association of New York, the neighborhood has the highest concentration of Arabic speakers in the city.

Last year, the Islamic Society of Bay Ridge held an open house to combat what it considered misperceptions of Islam being perpetuated by politicians, including Donald Trump.

This afternoon, Officer Elsokary joined with Brooklyn Borough President Eric Adams to call for prosecutors to toughen their stance against those accused of hate crimes by refusing to offer them plea bargains.
