Robert Johnson told local news station ABC11 he was recording police after their arrival at a local bar where a friend got in an altercation with the staff, back in February.

He claims he kept a "safe distance - just videotaping," before an officer told him they would take his phone.

Johnson reported to ABC11: "He said that he needed my phone for evidence cause I was videotaping the arrest, but I know that wasn't right, so I kept taping."

The officer allegedly took his phone: "He grabbed my other hand that was not in a cast and twisted it back and was trying to slam me on my face which eventually happened."

In the video, you can hear someone ask Johnson -- reportedly that same officer -- "how do you stop your phone?"

Johnson was then arrested for resisting and obstructing an arrest. A spokesperson for the police department reportedly acknowledged the officer made a mistake, but offered no further details. Johnson's charges were eventually dropped and he got his cell phone back. Yet, as he was already on probation following a 2013 assault, the arrest still shows up online. He tells ABC11: "It looks bad if I try to get a job, I go to school, it just ruins a reputation...you should never get your phone taken or taken to jail just for videotaping an arrest."
