Chris Brown will have to postpone his European "Fan Appreciation" tour after UK immigration refused to grant him an entry visa. In a statement the Home Office (as UK immigration is known) said it had the right to deny entry to anyone "guilty of a serious criminal offense. "Public safety is one of our primary concerns," it added. Brown had concert dates in three UK cities including London, Manchester and Glasgow. Earlier he tweeted (and then deleted) a message to his fans: "Sorry to all my fans in europe (sic)! I'm pretty sure y'all know. my entry was denied in your country. i love you."
