On 22 April 2012, Chen escaped from house arrest. Chen's fellow activist Hu Jia stated that Chen had been planning escape for a long time, and had previously attempted to dig a tunnel for escape. In the weeks leading up to his escape, Chen gave his guards the impression that he was ill in bed, and stopped appearing outside the house, which allowed him several days before any absence would be discovered. Under cover of darkness and with the help of his wife, Chen climbed over the wall around his house, breaking his foot in the process.
