Bembridge Coastguard Rescue Team and Ryde Initial Response Team were tasked to the Ryde Seafront area after a distress flare was spotted between Simeon Rec and Appley Park, prompting fears a sailor could be in danger.
A search of the area was conducted, however no signs of any persons in danger were found.
Officers from Hampshire Constabulary are now looking into reports of two youths running from the area, with the incident – which happened between 02:00 and 04:30 – being treated as a false alarm.
Anyone with information is asked to call Police on 101.
