B2K’s Raz B Breaks Window and Climbs Onto Hospital Roof, Cops Referred to as

Alarming behavior from Raz B — breaking a window at a hospital and climbing onto the building’s roof, forcing police to get involved … TMZ Hip Hop has learned.

The scary incident went down Thursday in Kansas City, the morning after the B2K singer posted a video on Instagram where he repeatedly said he didn’t feel safe.

Raz B claimed to be at a Hilton hotel in Kansas City on Wednesday night, saying he was “fighting to stay alive” and didn’t want to “have this surgery here.” He also posted the address for a Kansas City hospital.

TMZ obtained video showing Raz on a roof of that same hospital … as shocked onlookers watched in horror from a window across the way.

Law enforcement tells TMZ … officers were dispatched to Saint Luke’s Hospital at 10:20 AM Thursday after being called by off-duty cops and hospital security.

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

There was concern Raz might jump off the ledge … cops say the fire department responded to the scene too and placed mats down below, just in case he did.

Police say a negotiator got involved too, and he ultimately came back through the window peacefully and was treated by medical staff.
