The pensioner, known as Elizabeth, accidentally locked herself inside her Feltham home and could not get to the food left outside the property. A passerby took advantage of the situation and snatched the bags of supplies she had ordered online.
The Metropolitan Police said the woman, who has no friends or family nearby, had no food left in her home and resorted to searching through her bin in a bid to stay alive.
After officers were notified about her plight they arrived with groceries and toiletries.
A spokesperson for the Met Police shared the story on the force’s Facebook page.
Police found Elizabeth locked insider her home with nothing to eat
They said Elizabeth had been "overwhelmed with the officer's selflessness and generosity and thanked them for their help".
They said: “Officers came to the aid of a pensioner who was trapped indoors and left to starve.”
They continued: “Unfortunately, she had managed to lock herself in and while confined to her home with no way of leaving, a callous individual took advantage of the situation and stole the food from the pensioner’s front doorstep, leaving her with nothing.”
After gaining entry, the two policemen found she had no food in the fridge or cupboards.
They headed to the shops and soon afterwards returned with much-needed supplies.
"This is a remarkable example of what lengths our officers will go to, to protect local residents during this very challenging time," the post read.
"Well done PC's Matt Hodge and Pat Peltier!"
