The body of a young man was discovered in a toilet block in Alexandra Park this afternoon (Monday).
The 36-year-old is believed to have collapsed while in the men’s toilets before being found at around 11.20am.
Police officers and paramedics were called to the scene by the park’s bowling green.
Paramedics tried to resuscitate him but the man was declared dead.
A Sussex Police spokesman said the man’s death is being treated as unexplained at this stage.
