The trio can be seen stamping on their victim after minor provocation at Leicester Square tube station in London at 2.15am after a night out.
Despite attempts to hold them back, one woman in a white dress rushes back in repeatedly to stamp on the man on the floor.
Tylah-Jo Bryan, Amarnih Lewis-Daniel and Michael ODoherty – who goes by the name Tamzin Lush – assaulted the man first.
Footage shows Transport for London (TfL) staff, men in suits and others on the platform trying to stop the attack but they keep coming back for more.
