Hong Kong's businesses will likely foot the bill for vandalism inflicted over the past four months during the territory's most violent protests in living memory as few of them bought insurance coverage for riot damage, industry insiders said.

Businesses big and small have suffered smashed windows, graffiti and even fire for their perceived support of mainland China by activists concerned that the central government in Beijing is exerting increased control over the special administrative region at the cost of democratic freedoms.

Displaying a banner in support of the police — who protesters have complained of being heavy-handed — was enough to see a small video game shop in western New Territories vandalized four times this month.
