One resident, who lives close to the scene of the discovery said several police cars had been seen 'flying' towards the sea front.
She said: "The police came flying past with the blue lights flashing.
"There were four or five cars and they were all heading towards that stretch of sea wall.
"You could tell it was something serious because there were a number of vehicles.
"There is police tape across the path."
It has been reported on social media that the body was that of a 'young man'
A Police spokesman said officers have not yet been able to establish the age of the man.
The force said the body was not believed to be that of on-the-run convicted sex offender John Gilbert Blacktop.
