Police have issued a warning about taking legal highs after a half-naked woman was caught on camera in Cornwall sprawled across a bench and touching herself in the middle of the day.
A video of the incident on Monday afternoon was posted to Facebook and attracted tens of thousands of views in less than three hours before it was removed.
The clip depicts the woman slumped on a bench in a Cornwall town centre, take off her trousers and underwear before performing a sex act.
Devon and Cornwall police said they received two calls from members of the public concerned for the woman's wellbeing.
Sergeant Marc Sayers said: "The person who called us described a woman who was half naked and they said she appeared to be in drink or drugs."
He said the second person described the woman falling over.
Police officers arrived at the scene, by which time the woman had placed her trousers back on.
Paramedics from South Western Ambulance Service were called and she was left in their care for medical attention.
Mr Sayers said they had not received any calls complaining of the female acting indecently and as such could not confirm if a criminal offence had been committed.
He said on information he had received about the incident that there was a "high probability of taking a New Psychoactive Substance or what are otherwise known as so-called legal highs. Alcohol does not make you lose control in this manner."
Police are reviewing the video to see if any offence has been committed.
Anyone with information is asked to call police on 101.
