Man yells ‘chemical warfare’ and waves towel in hospital

Authorities say a Connecticut hospital’s emergency room was evacuated when a man took a towel out of a backpack and started yelling “chemical warfare.”

Police say the man was acting irrationally when he walked into the Yale New Haven Hospital emergency room at about 10 p.m. Monday.

Rick Fontana, director of the New Haven Office of Emergency Management, says 35 people were evacuated and three people — two hospital employees and a police officer — who came into contact with the towel were decontaminated as a precaution. No one showed any signs of illness.

Officials say the man left the scene and was not taken into custody.

Police called it an isolated incident.

The hospital’s emergency room remained open.
