According to the Derby Telegraph, over 600 fans bought tickets to see the G-Unit member perform at club T-Five tomorrow (May 5) in Derby.
The court order, which was granted by Southern Derbyshire magistrates yesterday, forbids the club from opening for 24 hours starting at noon on Saturday.
"It's not particularly the individual, although it is a music genre that glorifies guns and violence," Chief Inspector Gary Parkin said. "Because of the lack of preparation time and us finding out at short notice, there hasn't been time to put the proper contingencies in place to make sure the event goes off in a safe environment."
Police are working with local promoters to ensure that the 600 ticket holders are aware the concert has been canceled.
"I accept that in the current climate, trading is difficult and licensees need to make a living but I have to balance that with the safety of people living in and visiting Derby. We're not saying this type of thing won't happen in Derby but it needs to happen in the right circumstances," Chief Parkin said.
