A man who accused Kanye West of attacking him reportedly failed to show up for his follow-up interview with police in Beverly Hills, California. The Stronger hitmaker is at the centre of a police investigation over allegations he assaulted a man who made nasty comments to the rapper's fiancee Kim Kardashian in Los Angeles earlier this month (13Jan14). However, the unidentified man did not attend his follow-up interview with cops, a law enforcement source tells E! News. The meeting is usually set so the victim can explain the extent of their injuries and detail any treatment or medical examinations they received. Beverly Hills Police have yet to comment.
