Wong Swee Chin, known professionally as Edmund Tan / Louis Ling / Botak Chin (3 March 1951–11 June 1981) was a Malaysian criminal and gangster. He rose to fame as one of the most notorious and dangerous gangsters during the 1960s and 1970s. He and his friend Kevin Yee Kai Kit were known for conducting armed robberies, which in a few cases involved huge amounts of cash. He was respected by the Chinese Hakka community and often regarded as modern-age Robin Hood, as some say he shared the cash from the robberies with the poor. On the evening of 16 February 1976, he was arrested by the police. He was executed on 11 June 1981 in Pudu Prison.
