Keith Olbermann later tweeted, "this may be it for NYPD Com'r Kelly". Via MyFoxNewYork:

(MYFOXNY) - While covering the Occupy Wall Street protests on Wednesday night, Fox 5 photographer Roy Isen was hit in the eyes by mace from a police officer and Fox 5 reporter Dick Brennan was hit by an officer's baton.

The protests on Wall Street continued to grow all day. The rallies and their participants are showing no signs of slowing down.

In the evening, crowds surged past barriers and NYPD officers moved in to contain the protesters. By many accounts, mayhem broke out.

Officers, many wearing white shorts indicating supervisor rank, swatted protesters with batons and sprayed them with mace, video from the scene showed.

Fox 5's Isen and Brennan were there and witnessed the chaos. At one point, Brennan was hit in the abdomen by a police baton and Isen got irritant in his eyes. Both journalists were all right and continued to cover the protests and arrests.

And this from a Fox affiliate:

What was once a protest of powerful Wall Street financial firms and banks is growing into a larger movement about the working class, employment, poverty, education, and more.
