A medical resident recovering from gunshot wounds in a doctor's assault-rifle attack at a New York hospital has sued the institution and a gun shop.

Justin Timperio sued Wednesday in Manhattan federal court, seeking unspecified damages.

Authorities say a doctor who had been forced to resign from Bronx Lebanon Hospital two years earlier amid a sexual harassment claim opened fire inside the hospital on June 30, killing a doctor and hurting six others. Police say the doctor, Henry Bello, killed himself at the scene.

The lawsuit said the hospital had insufficient security to stop Bello from entering the grounds even though a nurse and a security guard were injured in a 2011 shooting there.

It also blamed the shooting on a Schenectady, New York, gun shop.

The hospital did not immediately comment on the lawsuit.
