Campaigners demanding a boycott of Japanese goods scuffled with security guards yesterday at Sogo department store in Causeway Bay.
The trouble erupted after two members of the 123 Democratic Alliance, Sung King-fai and Chu Cho-yan, entered the store's basement.
Guards tried to force the protesters, who wore red headbands and signboards with anti-Japanese slogans, to leave.
Mr Sung said: 'I'm here to buy things. Don't push me! Why are you stopping me?' A guard replied: 'You can't come in here dressed like this. This is a private area.' A shoe counter under renovation collapsed and sales staff called police.
The scuffle lasted about 10 minutes. Management then escorted Mr Sung and Mr Chu as they spent $51.20 on non-Japanese distilled water, chocolates and papayas.
Sogo management declined to comment, but the protesters reported an alleged assault to the police. They were sent to hospital for a medical examination.
