The shooter in Monday’s massacre at Virginia Tech was hospitalized in 2005 after female students complained he stalked them, law enforcement officials said Tuesday. Virginia Tech Police Chief Wendell Flinchum said his department received one complaint in November 2005 from a female student who said Cho Seung-Hui bothered her with phone calls and in-person contact. The woman did not press charges, Flinchum said, but officers did talk to Cho about his conduct.

A month later, around the same time concerns surfaced over Cho’s violent creative writing assignments, another female student complained about Cho sending her instant messages. Again, no charges were pressed.
