(CNN) -- The American man who swam to Aung San Suu Kyi's home in Myanmar said Thursday he still believes he did the right thing, even though his visit led to an extension of the pro-democracy leader's house arrest. John Yettaw told Aung San Suu Kyi he had a vision she would be murdered. John Yettaw, 53, swam across a lake to Suu Kyi's home in May and stayed for two days before authorities arrested him along with Suu Kyi and two of her staff. His presence violated the terms of Suu Kyi's house arrest -- which was about to expire -- leading a judge to extend it by another 18 months.
