The reward comes as another swastika was discovered nearby in the same far North Dallas neighborhood.
David Schneider and couple of other neighbors are putting up the $1,500 reward.
Schneider lives across the street from Congregation Toras Chaim, a synagogue. He had sued to keep it from operating in the neighborhood because he was concerned about overcrowding neighborhood streets, but the case was thrown out.
Schneider says despite he and Rabbi Yaakov Rich's past differences, hate crimes cannot be tolerated.
Rich believes the perpetrator was likely a misguided juvenile.
The City of Dallas filed a lawsuit against the synagogue earlier this month for meeting in a private home. That lawsuit is ongoing.
