(JTA) — The Anti-Defamation League has offered a $2,500 reward for assistance in catching whoever spray-painted swastikas at a Jewish fraternity house at the University of California, Davis.

The reward, which was announced by Davis police on Tuesday and reported by the Sacramento Bee, is for information leading to the arrest and conviction of those who painted the two swastikas between 2 a.m. and 9:30 a.m. Saturday.

The swastikas appeared at the off-campus house of Alpha Epsilon Pi two days after the U.C. Davis student senate passed a divestment resolution targeting Israel.

In response to the vandalism, Andrew Borans, the national executive of AEPi, announced in a statement that “Alpha Epsilon Pi International has dispatched staff and security experts to Davis to assure that our brothers are safe in their university and safe when expressing their Judaism and support for Israel.”

In addition, an online petition emanding “immediate condemnation of this hateful act from all UC Davis administrative officials as well as from every single ASUCD elected representative” had garnered 16,037 signatures by Wednesday.

U.C. Davis Chancellor Linda Katehi issued a statement condemning the vandalism attack on Saturday, the same day that the swastikas were found.
