According to the Force, the young teen was bitten by a small black dog while she was standing outside the Co-op at Charing Cross around 17:10 on Tuesday (29 September).
Officers explained: “The girl, in a red jumper and black leggings, was crossing the zebra crossing outside the shop was bitten on the leg by a small black dog, possibly a Manchester Terrier or Miniature Pinscher who ran up to her whilst she was on the road.
“It’s believed that the dog was with a man standing outside the shop at the time. He also had another similar dog with him.”
The girl was subsequently treated at A&E, though her injuries were described as “minor.”
