The death of a 36-year-old man whose body was found Wednesday at a campsite near the Fore River Parkway Trail System is suspicious, but there is no danger to the public, Portland police said early Thursday.

Police were called to a campsite along the Fore River Parkway at the end of Frederic Street at 4:40 p.m. for someone in need of medical assistance. Officers found the man deceased, said Maj. Robert Martin.

Martin said the man’s death is considered suspicious and an autopsy will be done by the Office of the Chief Medical Examiner to determine the cause and manner of death.

Police have not released the man’s name or any other details about what they believe happened at the campsite.

The body was found near Northern Light Mercy Hospital. Security measures at the hospital went into effect, but were relaxed once police told the hospital there was no danger, News Center Maine reported.
