Birmingham City footballer Jermaine Pennant was thrown out of a nightclub party for US rapper Kanye West following the NEC Arena concert.
The 23-year-old winger reportedly brawled with doormen at The Works, in Broad Street, in the early hours of yesterday after being asked to leave.
An eyewitness said Pennant was shouting and swearing and had to be restrained by security staff.
Paul Smith, aged 42, from Sutton Coldfield, said: "They tried to calm him down and he refused to cooperate. At least five doormen arrived and manhandled him down the stairs and out to the front door of the club.
"Pennant then started brawling with them and had to be restrained by a friend and a woman police officer who was on patrol on Broad Street and ran over when she saw the fracas."
Pennant was said to have been calmed down by a woman police officer before being allowed home to his apartment in the Centenary Plaza complex.
The party at the popular city club had been billed as an after-show event for West but the American star never made it to the show, where he was supposed to perform four of his most popular tracks to thousands of revellers, following security concerns after the NEC shooting.
Pennant has previously been jailed for drink-driving and sent home from the club's training ground following a drink-related incident.
The player's agent, Sky Andrew, played down the nightclub incident as the kind of event that happens "every time" the Premiership star goes out.
He said his client was approached by a group of students, one apparently a Liverpool fan, who started "giving him some stick" before bouncers asked the Blues star to leave to prevent any trouble.
Promoter Jordan Grainger who organised the after-show party at The Works confirmed his security staff had dealt with Jermaine Pennant after complaints he had been abusive to other guests.
