SHI TAO: Journalist, in jail
Mr Shi was jailed for sending on to foreign websites an e-mail from the ruling Communist Party warning journalists not to cover the 15th anniversary of the Tiananmen Square massacre in 2004.
His case has become a cause celebre for free speech campaigners - not least because internet firm Yahoo was accused of informing on him.
The US-based web giant passed on details of his whereabouts to the authorities, and has since apologised to Shi Tao's mother.
