This stems from an incident on the afternoon of March 4, 2010 in the 7700 block of Roosevelt Boulevard.
Investigators said Officer Aleksande Shwarz, 54, was on duty at the time and arrested a man Shwarz claimed assaulted him.
However, Internal Affairs and the D.A.'s office concluded Shwarz made the story up.
It was not known why Shwarz allegedly fabricated the story.
The man who was arrested was released a short time after the arrest, and the District Attorney's Office declined charges in the case.
Shwarz, a 21 year veteran assigned to the 2nd District, was charged with simple assault, unsworn falsification to authorities and abuse of office.
Commissioner Ramsey has suspended Shwarz for 30 days with the intent to dismiss.
