For the second time in the past four months, swastikas were discovered scrawled at Northeastern University early Sunday morning, according to a letter sent to students by university President Joseph E. Aoun.

A resident assistant found the Nazi symbol at approximately 1:30 a.m. drawn on a white board in a student common area of the university’s International Village dormitory.

Northeastern Police are actively investigating the incident, according to Aoun’s letter.
