Lt. Jonathan Josey of the Philadelphia Police Department was captured on video last September punching a woman in the face at a parade. VIDEO here:
Unbelievably, he'll be back to work with full back pay.
The arbitrator ruled on Monday that Josey's firing was "improper" and he will be reinstated with full benefits and back pay.
Josey was fired after he was videotaped punching the victim, Aida Guzman, after the Puerto Rican Day parade last September.
She was struck in the face and fell to the ground.
During his assault trial earlier this year, Josey testified that he was trying to knock a beer bottle out of Guzman's grasp.
At the time, the judge said the video was 'disturbing,' but said there was insufficient evidence to convict Josey of simple assault and he was acquitted.
Police Commissioner Charles Ramsey fought to have the firing upheld.
