The scene at the Occupy Oakland encampment in Frank Ogawa Plaza—renamed Oscar Grant Plaza by its new residents - remains tense this evening as protesters continuously try to take back the park despite tear gas.

SFGate reports:

Police gave repeated warnings to protesters to disperse from the entrance to Frank Ogawa Plaza at 14th Street and Broadway before firing several tear gas canisters into the crowd at about 7:45 p.m. Police had announced over a loudspeaker that those who refused to leave could be targeted by "chemical agents."

Protesters scattered in both directions on Broadway as the tear gas canisters and several flash bang grenades went off. Regrouping, protesters tried to help one another and offered each other eye drops.

One wounded woman, who others said had been hit by one of the canisters, was carried away by two protesters.

Twitter was all abuzz with claims of rubber bullets being used, as well as the sonic canon. I'll have a bit more on the sonic canon later for you.

'AnonMedic' tweeted a photo of what is claimed to be a Occupy Oakland protester with a contusion from a rubber bullet, a pretty painful looking injury:

The Occupy Oakland twitter feed is stating that police have dispersed 5 rounds of tear gas at the protesters.

Now channel KTUV has just posted a disturbing video on their site that shows potesters trying to aid an injured person lying on the ground being targeted by a police officer who sends yet another tear gas canister hurling at the victim on the ground and those attempting to administer aid.

There will certainly be much more on the situation in Oakland for you later, as we continue to gather information on the arrest totals, and follow up on reports of injured protesters.
