SAN FRANCISCO -- One San Francisco police officer was slashed by a razor and another had his uniform torn and cheek cut in a clash with Occupy San Francisco protesters Saturday afternoon, authorities said. [...]
A female protester emerged from the crowd and an "exacto razor blade attached to a pen or pencil-like object," San Francisco police said in an email.
"The female slashed the inside of the officer's hand and ran back into the crowd before the officer had time to realize he was cut," police said.
In a second incident, a protester grabbed an officer's police radio and ran back into the crowd. As the officer attempted to retrieve it, a second protester blocked the officer and tore his uniform and cut his cheek, police said, intimating that a weapon had been used.
The officer retrieved his radio and both male demonstrators escaped into the crowd, police said.
