Apology follows threat to hundreds at Harvard

Cambridge, Massachusetts: Hundreds of students and other people affiliated with Harvard University who got a threatening email have received a second message with an apology that apparently came from the same email account.

Boston City Councilor at Large Michelle Wu is a Harvard graduate who received the emails. She says the email list appeared to target people with Asian surnames.

The second email that went out Saturday apologized and told recipients that the threatening email sent Friday was written by the writer's younger brother and he didn't mean it.

Friday's message threatened a mass shooting at Harvard on Saturday, prompting campus police to tighten security. A campus safety advisory was issued and a public event about the experiences of Asian Americans at Harvard was postponed.

Campus police continue to investigate.
