The martial arts expert S Suresh, who challenged Sungai Besar Umno chief Jamal Md Yunos to a duel, is alive and well.

A video circulating online claiming to depict his execution was instead of the shooting of Brazilian man Luciano Henrique Jesus de Oliveira, in Campinas, Brazil.

"I am still healthy and strong. Such slander should be stopped and appropriate action should be taken against those who make up such stories," Suresh said in a statement to Malaysiakini.
