China has released one of the last prisoners described as 'hooligans' who were jailed after the Tiananmen Square protests 20 years ago.

Liu Zhihua was 24 years old when he helped to organise a strike at a factory in Xiangtan to protest at the treatment of students in Tiananmen Square. He was imprisoned for the now-defunct crime of "hooliganism", and is the final trade union leader to be released.

According to Dui Hua, a human rights group, Liu has just been released from Loudi prison after his life sentence was commuted ahead of the 20th anniversary of the tragedy.

However, Liu will be unable to leave Xiangtan for the next five years and is prohibited from giving interviews.
