High explosives found by Harrow Estate
They were made safe by police who cornered off the site and began an investigation after Monday's find.
Mr Beardon said: "We had gone to the area like we do every week to clear the bins and disinfect, when I stumbled across what looked like a takeaw
ay coffee cup.
"But when I picked it up, it was labelled as explosives and had what looked like a lot of cartridges packed tightly inside."
He added: "I have never come across explosives before but we have discovered guns, dead pets, and people sleeping in bin areas before so we never rule anything out!Runners in the London
