On 4 May 2009, American citizen John Yettaw trespassed upon the residence of Burmese political prisoner Aung San Suu Kyi, two weeks before her scheduled release from house arrest on 27 May. This illegal visit prompted Suu Kyi's arrest on 13 May 2009. Yettaw himself was arrested by Burmese authorities on 6 May. He was charged on 14 May with illegally entering a restricted zone, illegal swimming and breaking immigration laws. It is illegal in Burma to have a guest stay overnight at one's home without notifying the authorities first.
