LOS ANGELES — A man stabbed a doctor and two nurses inside a Southern California hospital Friday before barricading himself inside the facility, authorities said. 

The Los Angeles Police Department got a call around 3:50 p.m. about a possible stabbing at Encino Hospital Medical Center in the San Fernando Valley, Officer Jeff Lee told USA TODAY. 

SWAT officers were on the way to the hospital in hopes to “bring this to a peaceful end,” Lee said. 

“He’s not running around the hospital. It appears that he’s in an area” and officers were “trying to talk him down,” fellow LAPD Officer Drake Madison said.

All three victims were transported to a local trauma center in critical condition, Nicholas Prange, a spokesman for the Los Angeles Fire Department, told USA TODAY.
