The man fell down and hit his head on the ground, which knocked him unconscious, police said. The suspect then riffled through his pockets and stole unknown items.
The wounded man was taken to a local hospital for treatment.
The suspect has not been arrested but is described as a 25-year-old man. He fled the scene before police arrived.
