Investigators released video from inside the Le Lai Deli, on South 23rd Street, back on October 29.
It shows two men attacking the victim with their fists and a pistol.
One of the assailants even stomped on the man's head while he was on the ground.
Police say the victim exchanged words with a woman shortly before the attack. She allegedly called for backup, triggering the assault.
If you recognize either suspect, you are urged to contact Philadelphia police.
