Labour Party member Stanley Ho Wai-hong was attacked by four white-clad men in Sai Kung - the second pan-democrat to be ambushed and assaulted within a week.
The 35-year-old Ho suffered fractures to bones in both hands and a head wound that needed stitches.
Ho was surrounded and beaten by four rod-wielding men as he walked past Man Yee Playground at around 4pm yesterday.
A witness said the white-clad assailants hit Ho on the head and also injured a foreigner passing by who tried to stop the attack.
The four men fled before police arrived.
Medical staff from a veterinary center of the Society for the Prevention of Cruelty to Animals took the injured Ho and the 34-year-old foreigner inside and treated the pair before an ambulance took them to Tseung Kwan O Hospital.
The Labour Party said the attack was planned and organized to create "white terror."
Ho ran for the Indigenous Inhabitant Representative Election in Sai Kung and organized screening of anti-fugitive bill documentaries. Ho requires a stick to help him with walking because of the effects of bone cancer, Labour Party lawmaker Fernando Cheung Chiu-hung noted.
Cheung believes recent attacks targeting pro-democracy figures are the work of triads.
Yesterday also saw targeted attacks on restaurants and coffee shops in Wan Chai and Kowloon Tong linked to firms or people that have taken stands against protest action.
They included Starbucks, Cova, EXP and Simplylife - linked to Maxims - McDonald's and Yoshinoya.
