I'm pretty sure some of the Grimm that broke into the city did it on their own... Like the Nevermore and stuff. Otherwise there was no point in the shot we got after Yang punched Mercury, showing the Goliath turning their attention towards Amity and changing direction towards Beacon.

Which brings us to what Coco said when the Nevermore landed over Amity "How did it get past the kingdom defences?"... Well, unless there were places that hunters didn't manage to cover, the Grimm must have overrun them.
