A shooting was reported near women's health clinic Planned Parenthood. Police have responded but, so far, had little information about the situation.
Police tweeted that the shooting took place on Centennial Boulevard which was "not secure." They asked media not to stage in the area and told shoppers in the area to stay in the stores.
"Right now we don't know if there are any hostages," police Sgt. Kevin Miyakusu told CNN. "It is a very fluid situation."
A witness told CNN that at least five officers were behind a building with their guns draw. Media has also reported several SWAT vehicles and more than a half-dozen police cars.
