NEW: Former Prime Minister Lee Kuan Yew is resting at home, his son's office says Lee was treated for an irregular heartbeat and "stroke-like symptoms" Singapore (CNN) -- Lee Kuan Yew, the founding father of Singapore and the man widely credited with molding the island nation into one of the world's most prosperous countries, has been released from the hospital, where he was treated for an irregular heartbeat and "stroke-like symptoms." The 89-year-old Lee was resting at home, according to a statement from the office of his son, Prime Minister Lee Hsien Loong. Commonly referred to by his initials, LKY, the elder Lee was Singapore's first prime minister after it gained independence from Malaysia in 1965. Lee was admitted to Singapore General Hospital on Saturday after experiencing a suspected transient ischaemic attack, or a brief disruption of blood flow to a part of the brain, the statement said. He molded Singapore into a major transport and financial services hub, with its port becoming one of the busiest around the globe. He voluntarily stepped down in 1990, the first Southeast Asian strongman to do so, and turned power over to Goh Chok Tong. February 18, 2013 -- Updated 0649 GMT (1449 HKT)
