Kanye West was under observation at a Los Angeles area hospital late Monday after the remaining dates of his national tour were abruptly canceled, multiple authorities familiar with the case told NBC News.
The admission followed a week of bizarre incidents during which the provocative rapper publicly railed against fellow music stars Beyoncé and Jay Z and retroactively endorsed President-elect Donald Trump.
A source familiar with the case said Los Angeles police responded to a medical welfare call about 1:20 p.m. (4:20 p.m. ET). No criminal activity was involved; the decision to hospitalize West was for his own health and safety, the sources said.
