the Rangoon Institute of Technology, where Phone Maw had been killed, they encountered a barbed wire barricade at Inya Lake and were attacked by riot police, resulting in several deaths and many arrests. Shortly after this, Ne Win's government closed the universities, and the movement went underground. Min Ko Naing continued to organize protesters and circulate posters of the violence at Inya Lake. Ne Win soon agreed to step down from office, and on 7 July, many imprisoned student activists were released. The following day, Min Ko Naing and others released the first statement in the name of the new All Burma Federation of Student Unions (ABFSU), an organization that had previously been known for its struggle against British colonial rule: "We shouldn't be swayed by the release of our fellow students. We will continue to fight."The ABSFU continued to release statements by Min Ko Naing urging protests to the military government, including one calling for a general strike on 8-8-88, a number which would later become synonymous with the movement itself. The 8-8-88 general strike drew hundreds of thousands of people to the streets of Yangon, and is widely seen as a turning point in the Burmese democracy movement. Min Ko Naing continued to speak to crowds in front of the US Embassy and Rangoon General Hospital, the sites of previous killings of protesters by Burmese government forces. He also arranged for the daughter of independence hero Aung San, Aung San Suu Kyi, to make her first speech to a crowd at Shwedagon Pagoda. Aung San Suu Kyi would go on to be elected prime minister in the 1990 general election, only to be denied office and imprisoned by the State Law and Order Restoration Council, the new military government. The protests lasted until 18 September, at which point soldiers opened fire on the crowds, resulting in at least 3,000 deaths. 15 years political imprisonment until 2004 Forced to go underground, Min Ko Naing continued his organizing work while moving from house to house every night to avoid arrest. After several months, he was captured along with other students. He was sentenced to 20 years' imprisonment, under Section 5(j) of the 1950 Emergency Provisions Act for instigating "disturbances to the detriment of law and order, peace and tranquility". His sentence was commuted to 10 years under a general amnesty in January 1993. He was considered a prisoner of conscience
