The incident happened about 2 p.m. Sunday at a home in the 800 block of Hawaii Avenue after someone at the residence called police to report that the nurse, identified Monday by police as Marchina Walker, removed her clothing and was acting erratically.

"It was in the patient's home. The patient was also battered," Palm Bay police Lt. Greg Latulippe told Local 6 News partner Florida Today. "The whole thing is unusual."

Walker, 21, was completely nude when officers arrived, according to police.

"The nurse apparently decided to take off her clothes and not act normally. The officers managed to convince her to be handcuffed. She is now in protective custody and was taken in for an evaluation," Latulippe said, adding that it was not immediately known what triggered the behavior.
