<p>Chief Kahley stated he does believe the 10-second video is disturbing, but added that it's the events leading up to the video that caused the officer to react.</p> 
<p>The video showing 23-year-old Melissa Penn, being punched by an unidentified police officer surfaced on social media early Monday morning.</p> 
<p>Police allege Penn caused a disturbance inside the popular bar on the 400 block of East Market Street in York before attacking the office and kneeing him several times. -- All of this happened before the cameras started rolling.</p> 
<p>Residents CBS21 News spoke with say seeing a woman being punched is hard to watch, regardless of the circumstance.</p> 
<p>"One thing we want to make sure of, is that our officers are doing their jobs correctly. We want to make sure they are treating people with respect. Again, I don't expect any officers to be punching bags," Chief Kahley said.</p> 
<p>Police say there is more video that may be released in the future. In the meantime, they are asking the public to not draw any conclusions.</p> 
<p>Police said the woman depicted in the video has been arrested, but did not release the charges pending against her.</p>
