It was the second such attack on Jimmy Sham, head of the Civil Human Rights Front, since protests escalated in the Asian financial hub in mid-June.
As many as five masked men wearing black and believed to be of non-Chinese origin had attacked Sham with hammers and knives for more than 10 seconds in the Mongkok district on the Kowloon peninsula, police said late on Wednesday. Police strongly condemned what they called a planned attack and vowed to investigate. Sham was in stable condition, a government spokesman said.
His group, which organized the million-strong marches in June, has planned a march on Sunday (October 21) in the neighboring district of Kowloon, but authorities have not yet confirmed it will be permitted.
