A huge machete blade has been found tucked away on a footbridge that residents say has become a hotspot for stashing items.
Other items that residents claim have been found under the bridge include huge sums of cash, jewellery and mobile phones.
A local resident came across the blade when cleaning the bridge near Headstone Lane Station in Harrow.
He said police had been made aware and that the knife had been taken to a “safe place”.
Residents felt it had been placed there for a “purpose” and that his find “might have saved a life”.
Posting in community Facebook group Fixit Harrow, the man who found the knife explained how the blade was the latest in a string of strange items hidden away on the bridge.
He said he has previously come across more than £5,000 in cash, a series of credit cards, jewellery and electronic goods such as tablets and mobile phones.
Cllr Peymana Assad said: “We work daily with the police to identify hotspots for anti-social behaviour, drugs and weapons, including regular weapon sweeps of the locality to remove hiding places and make sure the items are seized by the police.
“The council’s Community Safety Unit alongside the Safer Neighbourhood Policing teams ask that any residents witnessing acts of anti-social behaviour or crime report the incident to police via the non-emergency 101 or the emergency 999 numbers.
“We will work with the police to deal robustly with anyone identified to prevent further incidents having a negative impact on the local community.
“The safety of our residents is a priority for the council.”
The Metropolitan Police said the front desk of its Harrow branch was not immediately aware of this incident but it was being relayed to the local safer neighbourhood teams.
