Seven New York City police officers have been injured so far in clashes with protesters during Occupy Wall Street's Day of Action, an NYPD spokesman just told Metro.

 

The injuries includes cuts and bruises, said the cop, adding that some of the protesters are throwing vinegar in police officers' faces.

 

The most recent injury occurred at Broadway and Liberty Street, where an officer received a laceration to his hand after a protester threw a star-shaped object at him, said a police spokesman at DCPI.

 

The officer required 20 stitches to his left hand, said police.

 

Mayor Michael Bloomberg is visiting injured NYPD personnel at Bellevue Hospital right now, after which he will brief the public from the hospital's atrium.

 

There are numerous photos of protesters injured in the clashes and arrests; the exact numbers of injured protesters is unknown.
