Authorities are investigating the case where several swastikas spray-painted along a new bridge in the South Orange section of the South Mountain Reservation.

The photos show that at least seven swastikas splattered across the bridge with the words "they lie" and the numbers "666." The county officials said that the markings were made in purple, red, green and black which were cleaned by Tuesday afternoon after the park workers painted and sandblasted the bridge early in the morning.

Rabbi Jesse Olitzky of Congregation Beth El in the South Orange said that some of his congregants called him early in the morning after they saw the symbols.

Olitzky told to NJ Advance Media that, as a rabbi it is hard for me to deny that graffiti is just graffiti when I see that. It is an expression of hate, it is a hate symbol. We know that is not who we are in this town.

The graffiti follows bomb threats made all across the country at several religious facilities.

According to the state and federal law enforcement officials, the Katz Jewish Community Center in the Cherry Hill was forced to evacuate on Monday after a bomb threat. The hoax was one of at least eight similar threats across the New Jersey this year and one of dozens reported at the religious facilities across the U.S.

Sheriff Armando Fontoura said that his department is working with the Prosecutor's Bias Crime Unit to investigate.

Fontoura also said that, "this incident clearly supersedes mere mischievous behavior or graffiti and it cannot and will not be tolerated. We have already increased our uniformed and plainclothes patrols in the area. We have also deployed security cameras to this location."

Fontoura said that the Crimestoppers are offering up to $10,000 as a reward for anyone with information that leads to an arrest.
