Vassar alumnus Jacob Blumenfeld has been detained by Chinese authorities in Beijing, sources report. The twenty-six-year-old and four other activists unveiled a banner that read "Free Tibet" near the National Stadium at the Olympics in Beijing last night.
The banner was made up of small blue LED bulbs and was lit for twenty seconds before authorities stepped in.
Here is a quick clip of the banner before it was taken down.
