A 32-year-old Indian-origin bodybuilder in Singapore died of cardiac arrest, an hour after he stepped into the ring for a "celebrity" bout of Thai kick- boxing. Pradip Subramanian took on YouTube personality Steven Lim, 42, in his first-ever Muay Thai match at Marina Bay Sands for the inaugural event of the Asian Fighting Championship last evening. Subramanian, president of the World Bodybuilding and Physique Sports Federation (WBPF) Singapore, had replaced singer Sylvester Sim, who pulled out of the match citing insurance issues. Both Lim and Sim were contestants in the first "Singapore Idol" series in 2004.The match was called off in five minutes after the referee noticed Subramanian`s nose bleeding and declared Lim, 41, the winner by technical knockout. Subramanian took a few blows on his head but was still standing after the match ended. Later he appeared to be losing consciousness while in a corner, and had to be helped out of the ring and taken to hospital. dub-dob sounds.
