After gatecrashing fancy-dress Halloween festivities on Oct. 31, hundreds of Hong Kong protesters marked Guy Fawkes Day on Tuesday in the Tsim Sha Tsui tourist district of Kowloon by wearing the white, smiling Guy Fawkes masks made popular by hacker group Anonymous, the film "V for Vendetta" and protesters globally.

Some protesters vandalised traffic lights and a restaurant perceived as being pro-Beijing, prompting police to move in with the water cannon, as they have done on many nights during five months of demonstrations. Several protesters were detained while others ran off.
