The 25-year-old scrum half, who was dropped from the England squad by caretaker coach Stuart Lancaster after his previous misdemeanors, was found by police urinating against a building following a night out.
Care was arrested shortly after 03:00 on Sunday morning on the steps of a hotel near Leeds rail station in northern England.
Police say Care was "questioned and given a caution for being drunk and disorderly."
Care was quoted by the Daily Mail that the incident was down to "a small bladder (rather) than excessive drinking."
