A scrub-wearing suspect shot and critically injured a person inside a Philadelphia hospital early Monday, a report said.

The gunman shot the victim on the ninth floor of Thomas Jefferson University Hospital at about 12:10 a.m. before fleeing, WPVI reported.

The suspect made a getaway in a U-Haul that was last seen traveling toward I-95, the report said.

The shooter was wearing blue scrubs, a mask and a black backpack during the attack.

The victim was listed in critical condition early Monday.
