An out-of-town visitor wandered through town putting up stickers of swastikas Tuesday until a local, 21 year-old Noah Mohan, confronted him. A video of the encounter has spread on social media.

The stickers also had the words, "Stop Funding Israeli Terrorism." "I have 16 images in my inbox, and I know there are more," said Rabbi Jason Rubenstein, the executive director of Harvard Hillel.
