An 84-year-old woman was left trapped and starving after her food delivery was stolen.
The pensioner, named only as Elizabeth, had resorted to eating out of the rubbish bin to survive.
With no family or friends nearby, she had ordered shopping online but was unable to open her door to collect the delivery.
While stuck inside her home in Feltham, West London, her food was stolen from her doorstep.
Met Police officers PCs Matt Hodge and Pat Peltier arrived on the scene and gained entry to the home.
Writing on Facebook, the Met Police said: “The officers swiftly gained entry to the property and on seeing that her fridge had literally no food in and hearing that she had resorted to eating out of the rubbish bin to survive, they immediately decamped to the local shops and purchased food, drinks, toiletries and a few other necessities to fill her home and make her feel more comfortable.
“She was overwhelmed with the officer’s selflessness and generosity and thanked them for their help.
“The officers have put the necessary action in place to ensure this heart-breaking situation doesn’t happen again.
“This is a remarkable example of what lengths our officers will go to, to protect local residents during this very challenging time.”
