A female Northwestern student reported being sexually assaulted by a male Monday night in a University residence hall, according to an NU security alert.

The alert said the student had previous communication with the male. The two met at a Chicago Transit Authority station and he then assaulted the student in her residence hall room between 6:30 p.m. and 7:30 p.m.

The male is not believed to be affiliated with NU, according to the alert.

This is at least the second sexual assault reported at NU in March. The first occurred Feb. 27 at the Evans Scholarship House but was not reported until four days after.

University Police Deputy Chief Dan McAleer said an emergency alert was sent on Monday because the student notified the police the same day the incident occurred. An emergency alert was not sent out for the other sexual assault incident because it was reported four days after it occurred, he said.

This post was updated April 1 at 1:33 a.m. with information from Dan McAleer and at 3:26 p.m. for clarity.
