A group of Harvard University students and faculty received an email containing a death threat, followed by an apology, but the school's police are investigating the matter all together.

According to the Harvard Crimson, the police are still categorizing the investigation into the emails as "open and ongoing" despite the odd apology note. On Friday, the threatening email apparently came from outside the U.S. and found about 100 people, mostly students.

Early Saturday, the Harvard Police alerted the school's community that they were aware of the threat and were enhancing security. Later Saturday, another person using the same email address issued an apology.

The new emailer claimed to be 15, that the threat was from a younger sibling and that they were in France. Both the threat and the apology were written with poor English language and grammar, the Crimson reported.

Michelle Wu, Boston City councilor at large and a Harvard graduate, told the Associated Press that she received the emails. She also said they appeared to target people of Asian descent, based on their surnames. The threat claimed a mass shooting would take place on Saturday at "11 o'clock."

Steven G. Catalano, a spokesman for the Harvard Police, said in the email Saturday that the threat "appears at this time that the threat may not be credible." Security was heightened regardless, but Harvard's campus was business as usual otherwise.

According to a copy the Crimson reported obtaining, the email contained racial slurs, but addressed "all students at Harvard." Some students said they received the same email from a Gmail account, which was traced to a sender named Huy Dinh.

Some of the students who received the Gmail message had previously been contacted by Dinh, whose address responded to the Crimson for comment. The sender did not take ownership of the threat and asked for the student-run newspaper to take down its article on the matter.
