BOSTON — A Boston man remains in the hospital after police say he fell naked through the ceiling of a women’s bathroom at Logan Airport and then assaulted an elderly man.

Prosecutors said Monday that 26-year-old Cameron Shenk is still at Massachusetts General Hospital, and his arraignment time is uncertain.

Shenk faces charges including attempted murder, assault and battery on a person over 60, and lewd and lascivious conduct.

Police say Shenk fell through the ceiling at about noon Saturday. Authorities say he had apparently sneaked into the bathroom, undressed inside a stall and climbed into the ceiling crawl space. He was injured in the fall.

Investigators say the man fled the bathroom and assaulted an 84-year-old man he encountered.

It’s unclear if Shenk had retained an attorney.
