AN UNEXPLODED hand grenade has been found a few metres from a public footpath in Tilgate Park.
A Tilgate Nature Centre employee found the weapon shortly after midday last Thursday, close to the Walled Garden Café.
After the discovery of the grenade, described as "rusty", police were called and the area cordoned off.
A bomb disposal team from Aldershot, in Hampshire, arrived just after 2pm.
Having examined the grenade they took it away for disposal without detonating it.
The weapon had been found by Emile Ellis – who was in his first week in the job at the nature centre.
Emile discovered the device when he was planting bulbs for next spring near the café.
Simon Woodard, the manager of the nature centre, said: "One of the gardeners, Emile, found it on his first week. It was an exciting start to his time here.
"I was quite surprised and shocked at them finding a grenade, but we have come across them before."
Alan Dixon, the manager of Tilgate Park, said that in his 23 years of working at the park three grenades have been found.
"My reaction was 'Here we go again'," he said. "But it is not a problem, because we know what to do."
Tilgate Nature Centre staff roped off the area where the grenade was found and contacted police.
Mr Dixon said: "We have a procedure if anything like that is found by a member of staff. We have a certain sequence, which starts with calling police.
"The police come and they take over. They put an exclusion area around it so the public couldn't gain access. Then the bomb squad arrived."
Mr Dixon explained that Tilgate Park was used as a base for Canadian and Polish soldiers during World War Two – who camped there in preparation for D-Day. Two hand grenades were previously found in Tilgate Lake in 2010.
When employees first start working at the park they are made aware of the potential of finding explosives.
