Two female Georgetown students reported that a strange male entered their homes this week, and investigators believe the alleged culprit – known as “the Georgetown cuddler” – is connected to 11 similar incidents in the last year and a half.

The two most recent break-ins occurred on Sunday and Tuesday and, like in the other cases, the victim awoke early in the morning to find a strange male next to them in bed. In all of the cases, two of which happened on Georgetown’s campus and nine in homes in the area, the man fled when the victim woke up. The Tuesday case reportedly involved a sexual assault, according to public safety announcements released by Georgetown.

To protect students, Georgetown has added extra public safety officers and cooperated with the Metropolitan Police Department’s investigation, Andy Pino, a spokesman for Georgetown, said in an e-mail.

Several similar unlawful entries and assaults were reported over the last year and a half, many involving a white or Hispanic male.

Though the incidents have been centered in Georgetown, students should check their doors and first floor windows before they go to sleep, GW University Police Department Chief Dolores Stafford said.
