A lawyer for an anti-Wall Street protester hit by pepper spray while being detained by police asked the Manhattan District Attorney to arrest the police inspector at the center of the controversy.

In letter sent Tuesday on behalf of protester Kaylee Dedrick to Manhattan District Attorney Cyrus Vance, attorney Ronald Kuby demands that the prosecutor file assault charges against Deputy Inspector Anthony Bologna and place him under arrest.

Dedrick, a 24-year-old teacher's aide, was one of five women being held by police officers in orange plastic netting on Sept. 24 during an Occupy Wall Street demonstration near Manhattan's Union Square. Her lawyer wrote that she was treated at the emergency room after the pepper-spray incident and "suffered serious physical pain as a result of this attack."

Dedrick was not arrested in the incident, her lawyer wrote. Under the New York Police Department's Patrol Guide, Kuby noted in the letter, pepper spray may be used in "non-arrest situations only to subdue an emotionally disturbed person or against a dangerous animal."

Videos of the incident and a subsequent use of pepper spray involving Bologna were posted on YouTube and other websites. One of the YouTube postings to date has been viewed more than 1.4 million times. The Manhattan District Attorney's Office and New York Police Department have said that they are investigating the Sept. 24 incident.
