Nurse badly beaten by psycho patient: cops

A violent Brooklyn patient severely beat a Brookdale Hospital nurse Friday, leaving her in critical condition, cops said.

Kwincii Jones, 40, allegedly attacked nurse Evelyn Lynch, 69, after she checked on him in his hospital room at about 4:30 p.m., sources said.

Jones allegedly attacked for no apparent reason, the sources said.

Lynch was rushed to Kings County Hospital after the brutal attack so she could undergo brain surgery.

Hospital security held Jones down until cops arrived, the sources said.

“He hasn’t been charged yet, but he’s in our custody,” a police source said Friday night.
