The terrifying incident happened Thursday in Kansas City, the morning after the B2K singer posted a video on Instagram repeatedly saying he didn’t feel safe.

Raz B claimed to be at a Hilton hotel in Kansas City on Wednesday night and said he was “fighting to stay alive” and did not want to “have this surgery here.” He also posted the address of a Kansas City hospital.

TMZ obtained video showing Raz on the roof of that very hospital … while shocked onlookers looked on in horror from a window across the street.

Law enforcement told TMZ… that the officers were dispatched to Saint Luke’s Hospital at 10:20 am Thursday after being called by off-duty police officers and hospital security.

Police say that when they got there they determined that he had broken a window to climb onto the roof.

There was concern that Raz could jump off the ledge…police say the fire department also responded to the scene and placed mats underneath, in case he did.
