Detroit bus SWARMED by TWERKING women: "Seven Mile turned up that night"

Two women in the crowd of more than 100 people who partied in the street climbed up on the front of a bus. The driver was helpless, he was surrounded.

Tay and Jay, they called themselves, said they are bummed they missed it last Saturday morning.

"Seven Mile turned up that night and to all the shaky butts that night, I'm so glad y'all came out," quipped Tay, after seeing the video.

Not everyone is as enthusiastic about those so-called shaky butts, namely Detroit Police Deputy Chief Arnold Williams.

"It just boggles the imagination that people are out there just doing this," he said.

FOX 2 is told that DPD’s illegal block party detail – broke up a party that started at the Quarter Pass 7 rental hall, and spilled out into the streets - which is not allowed.
