VANCOUVER — Police in riot gear confronted more than 200 masked protesters who hurled newspaper boxes through the display windows of a popular department store selling Olympic souvenirs.
Seven people were arrested after officers carrying clubs and shields quashed the downtown protest on the opening day of competition at the Vancouver Olympics. There were no immediate reports of injuries.
Those arrested could face a variety of charges, including assault, Police Chief Jim Chu said. At least one could be charged with weapons possession for wrapping a bicycle chain around his fist and threatening passers-by. None of the protesters was immediately identified.
Chu said police knew in advance about the protest, but decided to move in once they knew "criminals" were involved.
Authorities said they were wary of masked anarchists who dress in black and use a tactic called "Black Block" to hide their identities. Among them was a loosely organized group from central Canada known to disrupt events that draw media coverage, police said.
"Their tactic is to hide within the ranks of legitimates protesters," Chu said.
He maintained that about half the protesters were "criminals intent ... on committing violent acts, including damage to property, including assaulting passers-by."
The protest was originally organized by the Olympic Resistance Network to "disturb 'business as usual'" in Vancouver. The ORN is an umbrella group for many causes surrounding the games, ranging from environmental to economic issues.
The most prominent involved native Indians who want to reclaim their property ("No Olympics on Stolen Ancient Land") and those angry over the amount of money spent on Olympics as opposed to public housing ("Homes Not Games").
Phone calls to the group were not immediately returned, but the group sent an e-mail Saturday saying 13 people were arrested.
After the demonstration, guards stood in front of Hudson Bay Company's broken windows, which were cordoned off with yellow police tape while Olympic tourists snapped photos. Workers removed the newspaper boxes.

"It's just unfortunate but nobody was hurt and that's the key," Gorman said. "We'll move on."
Riley Arcand lives near the store and called the vandalism "disgusting."
"We live in the most nicest part of town and everybody's excited about the Olympics," he said. "And then you have people who want to ruin it."
A police spokeswoman said rags soaked with vinegar were found at the scene, and some of the masked protesters were wearing goggles — which could suggest they were anticipating tear gas or pepper spray. Some protests groups tell supporters that rags soaked in vinegar and held to the mouth can minimize the effects of the chemicals.
The group said three people were arrested in that protest. The police reported just one arrest.
Chu said the police will continue to monitor protests but do not want to impede freedom of speech.
"We still recognize that there are legitimate protests out there that want to send messages and exercise their rights," he said.
