Ich zitiere hier mal aus dem reddit, auf wenn alles höchst spekulativ ist und mit Vorsicht zu genießen. Stammt wohl von jemanden der sich im Stuttgarter Rotlicht Bezirk auskennt und wohl näheres wissen will.

Sooo, Mister Kevin Großkreutz partied with [VfB]-U17-players (year of birth 2000/2001) in Stuttgart's night club "Perkin's Park" - Abi-Party1 Under 18-year-olds...He treat them to the club lounge and bottles, he bought them eeeverything. Right after, they went to Burger King, where he bought them eeeverything as well. Then, a few of the U17-players went home.
Following, the "kaputten Kanacken" 2 of the VfB went to a brothel. He bought aaall of them everything again, he also treat himself to a girl.
He didn't cum after 20 minutes, got angry at the girl and refused to pay her but eventually he still did.
When he left the brothel, a few guys of our age recognized him and said to him: "You've got training tomorrow, don't you?"
KG responded with: "Bla bla, screw training, that's none of your business!" And that went on and on [as in: he continued to smack-talk them]
Unfortunately for Großkreutz, he took on the wrong guys and they really gave him hell [punching him]. Not like in the papers, one punch, two punches, no, noo, he got properly fucked.
Then a VfB youth player found him and raised Großkreutz' head, blood all over him.
He then was hospitalized and a few of the young players, U18-year-olds, were driven to the football academy housing by the police.
That's the detailed report.

SOLLTE das stimmen, würds den Rausschmiss rechtfertigen.
