Original Story:

NBC is reporting that shots have been reported fired on the campus of Virginia Tech, the scene of a horrific massacre 4 years ago. The Virginia Tech website (which is currently down) released a warning about gunfire and the entire school is reportedly currently on lockdown.

"A police officer was shot at Virginia Tech on Thursday morning and campus officials warned everyone to seek shelter while an armed suspect was at large," said NBC.

The AP reported that "The suspect is described as a white male wearing gray sweat pants, gray hat with neon green brim, maroon hoodie and backpack."

In April of 2007, Virginia Tech was the site of one of the nation's worst school massacres, when 32 students were shot by 23-year-old South Korean Seung-Hui Cho, who killed himself in the ensuing pursuit by police.
