John Kennedy reports in the Global Voices Online:

Chinese citizen reporter Zhou “Zuola” Shuguang has just tweeted his own detention as it was happening on Wednesday afternoon China time.

(As of 17:15, Zuola was back at his computer; he seems to have been placed under some sort of ‘town arrest’. Updates below)

Zuola recently bought a Blackberry 8320 to help him with his citizen reporting endeavors, and he appears to have been able to use it along with Twitterberry to send out a few short messages as he was being escorted from his home into a vehicle and driven off.
