An-eight-year-old boy pulled out an unexploded grenade during a fishing trip on Grand Union canal.
Schoolboy Brando Smith, was fishing along with his twin brother Jacopo and best friend Nour, from a canal boat with their nanny James Bolton.
The trio were fishing with a magnet, and after pulling out an assortment of spanner and wrenches pullout out a rusty, muddy lump of iron. Suspecting what it was they immediately passed it to James, who carefully took it in his hands and placed in on an empty stretch of towpath before calling the police.
The police then brought in army experts who took it away for disposal.
James, who lives on the vessel in Maida Vale said the part he found the most terrifying was getting the children to safety and placing the grenade carefully on the ground. He said:
Police arrived within ten minutes and secured the area before calling the bomb squad - and called the fire service and London ambulance as a precaution.
Experts confirmed it was a WW2 grenade, but it was deemed safe enough to go to another location for disposal.
