The body of a man in his 40s has been found in a parked car north of Ventnor.
Police said they were called at 9.28am on Monday (May 30) after the discovery was made in Down Lane.
Multiple emergency services attended, amid a report from a witness that it was thought a chemical could have been involved.
This remains unconfirmed by police, who said on Monday afternoon that the incident was "not being treated as suspicious", and that a file is being prepared for the Coroner.
The man's next of kin have been informed.
