Kanye West's debut performance at the NEC Arena near Solihull in the UK was tainted by a shooting that left two security guards of the venue wounded.
West was in town on the final date of his five-date Touch The Sky Tour, which ended with an appearance at the NEC Arena.
According to police the incident started when a man was ejected for entering the concert without a ticket.
The man later returned and fired four to eight shots at the security guards, striking a 45-year-old in the face, stomach and foot.
"My thoughts and prayers are with the two stewards who were injured last night," West said in a statement.
The 45-year-old employee of the venue underwent an operation at an undisclosed hospital, while the second security guard suffered minor injuries.
"Firearms were discharged and two stewards were taken to hospital with gunshot wounds. Their injuries are not believed to be life-threatening," West Midlands Police said in a statement.
Over 12,000 people attended the concert and while police have two individuals in custody, officers said they were not significant arrests.
Police are seeking a black male, aged 18-22, 5 foot 10 inches, who was accompanied by a black female.
Officers are asking anyone with information to come forward.
