MIAMI (CBSMiami/AP) – A 32-year-old nursing assistant is accused of sexually assaulting four patients including one in a wheelchair and other disabled by a stroke at health care facilities in Florida where he’s worked over the past three years.

Clearwater police spokesman Rob Shaw tells the Tampa Bay Times that Falo Kane was brought in for questioning on Monday, confessed to the assaults and wrote an apology letter to the women. Shaw says they’re concerned there could be other victims.
