Coastguard rescue officers were called out following reports of distress flares being seen off the Corton cliffs area.
Teams from HM Coastguard Lowestoft and Southwold were called out at 10.50pm on Friday, July 21 to investigate in the Corton area.
A spokesman for the coastguards said: 'The team were paged by Humber Coastguard Operations Centre to reports of distress flares being seen off the Corton cliffs area.
'On arrival at the scene a search was commenced in numerous different areas to see if anything could be sighted. There was nothing untoward and no further sighting of flares.'
The team discovered, having spoken with locals, that there had been reports of people setting off fireworks around this time on Friday night, and the coastguard spokesman added: 'It seems that they then changed to flares.'
After no sightings were spotted, the team were stood down and returned to station.
