6ix9ine has been refused entry into the United Kingdom, forcing him to postpone two shows: one in London on Thursday, June 21 and another on Friday, June 22 in Manchester. The rapper and the venues in both cities confirmed the news by posting messages on social media that nonetheless provided little information as to why the rapper was denied entry.

The rapper’s management posted on the Facebook event page of the London concert that they had “an issue with immigration.” They added that although the two UK dates have been postponed until further notice, the rest of the rapper’s World Domination tour in Europe is still scheduled to go on according to schedule. The tour was originally scheduled to end in Belgium on July 6, but this might change now. The Manchester venue, Victoria Warehouse, released a statement confirming the rapper was “refused entry to the United Kingdom by UK Border Control on arrival into the country” on Thursday morning. The statement also confirmed the postponement of the Friday show and promised an update within 14 days.

6ix9ine is currently being investigated for the recent Chief Keef shooting in New York City. In May, he was arrested in Brooklyn for driving without a license. Earlier in May, he was wanted by police for allegedly choking a 16-year-old in a Houston mall. The UK’s Immigration Rules for Visitors website states that a person may be refused entry into the country if they have been convicted of a criminal offense and been sentenced to prison within a certain amount of time.

The UK has been cracking down on violence that it deems to be related to certain types of music. In particular, a drill rap group in London named 1011 were issued with a court order that bans them from making music without police permission.
