GREAT Train Robber Ronnie Biggs, 79, was released from prison yesterday on compassionate grounds as he is severely ill with pneumonia. The south Londoner was a member of the gang that robbed a mail train in 1963, stealing £2.6m. After a 30-year sentence, he escaped from prison and went on the run for 30 years. He lived in Brazil before returning to the UK in 2001 in search of free medical treatment.
