A bomb has been unearthed on Mill Hill in Shoreham.
According to Adur District Council, the Second World War mortar was unearthed yesterday by a team of ecologists.
They were contracted by the council to relocate some slow worms on the Adur-owned land when they made the discovery.
A council spokesman said that specialist police teams were contacted and a cordon put in place until the bomb was destroyed by a controlled explosion.
Philippa Recce, the council's parks and foreshore manager, said: "It was quite an unexpected discovery but thanks to the quick response of all involved, the situation was dealt with without anyone - including the slow worms - coming to harm."
