A hand grenade has reportedly been uncovered in a St Albans back garden.

Two landscapers, Adam and James, said they made the discovery while carrying out work at a property on Belmont Hill this afternoon (Tuesday, September 13).

Residents and visitors in Belmont Hill and the surrounding area - not far from A5183 Holywell Hill - have been evacuated.

Adam, one of the landscapers, said: "We were digging out the back of the garden when we found something which looked a bit like a grenade.

"It wasn't very deep at all, so we took it out. We later realised what it could be.

"The street was evacuated."
