Kanye West has been transferred to a Los Angeles hospital for observation late Monday night after a hectic week of erratic behavior. LA police responded to a medical welfare call at around 4:20 PM EST. Sources of NBC News say West has been hospitalized "for his own health and safety" and no criminal activity was involved. TMZ, though, is reporting Kanye was restrained by handcuffs during transport in the ambulance.

As you may already know, earlier today Kanye cancelled the remainder of his Saint Pablo tour (including NJ/NYC dates), following controversial comments about Donald Trump and former collaborators Jay-Z and Beyonce, as well as cutting his Sacramento show short only after three songs.

You may remember Kanye postponed several shows back in October, due to his wife Kim Kardashian-West's robbery in Paris. This story is developing, stay tuned.
