Malaysian-Chinese singer Gary Chaw Ge has been arrested for assault following a police investigation into a street brawl he had with Canto-pop singer-songwriter Justin Lo Ting-wei two weeks ago. Taiwan-based Chaw was arrested in the Central division's police station on Friday afternoon. He was released on bail to report back early next month, a police spokesman said. No charge has been laid. Assault carries a maximum penalty of one year in prison. Chaw, 30, and his 'sworn brother' Lo, hit the headlines after Chinese-language media reporters caught the duo brawling in Central and Admiralty in the early hours of September 23. Both singers issued public apologies the next day, but police, who said 'fighting on the street is a crime', launched an investigation. A district crime unit interviewed the two men later individually. Chaw, in his apology that day, said that he had 'made a serious mistake' but did not go into details as to what had provoked the fight. He admitted he had been drinking and might seek professional help for it. He also said he was prepared to co-operate with police. According to media reports, the duo had been at a bar in Peel Street, Central, at about 1am on September 23. Reporters then filmed Chaw apparently having an argument with Lo and pushing him to the ground. In another video clip, the singers were seen taking a taxi together to leave Central. The taxi stopped at Admiralty, where Chaw was seen getting out and stamping on someone sitting inside. Chaw was also seen threatening Lo with a road sign, but then put it down. They were then separated by friends.
