From guardian.co.uk:
The hundreds following amoiist on Twitter were used to his stream of messages. But they ended abruptly with two terse updates early yesterday morning.
“i have been arrested by Mawei police, SOS” he wrote. Then shortly afterwards: “Pls help me, I grasp the phone during police sleep.”
His followers quickly passed on his plea to other Twitterers. But since then there has been silence from amoiist – also known as Peter Guo, or Guo Bofeng – who is apparently the latest internet user to be caught up in an inquiry that began with claims of defamation but which police now say involves “state secrecy issues”.
