A man and his wife were attacked when the man tried to break up a fight on the street in West Philadelphia, police said.
The couple was walking home along the 5500 block of Jefferson Street around 2 a.m. when they came across a group of men and women fighting in the street, Philadelphia Police Department spokeswoman, Officer Tanya Little, said.
The man, 31, tried to intervene, at which point someone punched him in the face, causing him to later have to get six stitches to the inside and outside of his lip, Little said.
The man told police he was knocked to the ground, at which point he heard loud bangs that sounded like gunshots and saw his wife, 42, also on the ground and bleeding heavily from her face.

The man helped his wife up and took her to their house before driving to Mercy Catholic Medical Center, Little said. As he was pulling off, he saw another person fire two "air shots," the spokeswoman said.
Police said there was a large blood trail on the ground when they arrived, and they found bullet casings, as well.
