It happened around 10 p.m. at the store on the 1800 block of South Street.
The video, released Tuesday, shows some members of the group throwing items at store employees. Police said the employees suffered injuries.
Captain Sekou Kinebrew of the Philadelphia Police Department told reporters after the incident that a cashier attempted to intervene and he was hit in a head with a glass bottle.
"Between the things that they stole and the property damaged inside, it's between $6,000 and $7,000 in damage," said Captain Kinebrew.
Anyone with information is asked to call police at 215-686-TIPS (8477).
