Three men have been arrested on suspicion of assaulting outspoken former legislator Chim Pui-chung last month, police said on Friday.
The arrested men include two alleged assailants who punched and kicked the former finance sector legislator in Admiralty on November 20. The third man was a lookout.
Police said the men, whose ages range from 31 to 41, were arrested on Thursday afternoon and charged with assault causing bodily harm.
Chim, 66, said he was leaving his office in Admiralty and preparing to get into his car at about 3.40pm on that day when two assailants, who were wearing surgical masks, rushed him.
The assault left him with a swollen face and a few minor injuries. He reported the attack to police and had his injuries examined at Queen Mary Hospital.
Chim was a legislator from 1991 until his imprisonment for conspiring to forge documents in 1998. He returned to the Legislative Council from 2004 to this year. In 2007, he was treated for cancer.
