Police said they are asking for the public’s help in finding a female teen who was involved in spray painting hate graffiti at a Syosset school last month.

The teen was wearing a dark tank top, dark jeans, black shoes and a black costume mask, Nassau County police said.

Anyone with information on the teen or the crime is urged to call Crime Stoppers at 800-244-8477.

Police said the vandalism — swastikas, anti-Semitic writings, profanities and the name of the MS-13 street gang — were spray-painted on walls, doors and windows in the rear of Syosset High School on South Woods Road. The vandalism occurred between 2 a.m. and 4 a.m. Aug. 27.

A police spokeswoman said the images were spray-painted in “various” colors.

Syosset Superintendent Thomas Rogers has said the graffiti was also found at the adjacent South Woods Middle School.

Rogers described it as, “rude, crude and vulgar,” as well as “homophobic, misogynistic and anti-Semitic.”
