According to detectives, the suspects got into the school at 150 Jedwood Place by breaking a second floor window Thursday night.
Once inside the building, they used multiple cans of colored spray paint to graffiti the first, second and third floors of the school.
The superintendent described the graffiti as "extensive, vulgar and racist."
"One of those graffiti markings includes one swastika and the rest is derogatory comments about faculty and staff at the school," det. Sgt. Anthony Repalone said.
Some of the staff members saw the comments about themselves and were quite offended, officials said.
Police are confident that surveillance video at the school is giving them some leads...
"It may have captured the people responsible for this damage," Repalone said.
Police are not calling this a bias crime right now, but some sort of grudge against the faculty.
Several fire extinguishers were also discharged inside the school. '
Anyone with information is asked to contact Crime Stoppers at 1-800-244-TIPS. All callers will remain anonymous.
Summer school was cancelled for about 1,000 students because police did not want them contaminating the crime scene. That is a day of regents preps that cannot be made up.
