A swastika was found carved into a synagogue Saturday afternoon.
Surveillance video shows the vandal hopping a wall and then picking up a rock at the Chabad of Southern Nevada Synagogue.
Children who were in a nearby room watched as the man began carving something into a pillar.
Yossi Harlig, the Rabbi's son said he tried to scare off the man, before seeing what he drew.
"We went over and started knocking [on the window] and he noticed who it was," Harling said. "It's a swastika. It's not a good symbol."
Rabbi Shea Harlig said the vandal attacked while dozens of people were inside the synagogue for Saturday service.
"During the services, after it was holocaust remembrance a few days ago. That's a sick individual," Harlig said.
One congregate is now offering $1,000 reward for anyone leading to the arrest of the vandal.
"Maybe you should go visit a Holocaust museum or speak to a couple Holocaust survivors to understand what it is," Harlig said.
