A valley man was arrested as he was recording video of another arrest in downtown Las Vegas.

The man says he's a police accountability activist and claims he was wrongfully arrested near 4th and Fremont streets.

Kelly Patterson, the man on the other side of this camera, said he wasn't in the way but he was arrested anyway. He believes his arrest over the weekend wasn't fair.

"He basically pushed me backwards and then I am not sure exactly how any cops were involved because most were behind me but they all just jumped on me and threw me into the street and handcuffed me," Patterson said.

Patterson has been a part of Nevada Cop Block for the past 5 years.

He said, "Filming cops in action is a clear and neutral record of what exactly happened, so if the cops are in the right it shows that also."

But, as for what happened downtown on Saturday, "it's something I didn't see coming at all," he said.

13 Action News Crime and Safety Expert and retired Las Vegas police Lt. Randy Sutton said, "Cop Block, the group that Patterson is part of, is notorious for antagonizing cops."

"There was apparently some interaction before what we saw in this video because there was a reference made to it when the officer initially confronted the guy who had the camera," Sutton said.

Regardless of what happened prior, Sutton said the public has the a right to record.

"The reality is police cannot stop someone from video taping an action and in doing that is not in keeping up with the policies of the police department," Sutton said.

Patterson's attorney, Stephen Stubbs, said his client wrongfully spent 24 hours in jail and has been charged with obstructing a police officer and obstructing a vehicle in the roadway.

Patterson said he wants justice and his charges dropped.

Meanwhile, Las Vegas police internal affairs is investigating the case after reviewing the video provided by Stubbs.
