A passerby was disgusted to see a swarm of rats while taking her kids to school.

Footage shows the group of rats running about an alleyway off Franciscan Road in Tooting, south London at around 6:50am on October 2.

The "utterly disgusting" video was posted on social media platform Nextdoor by a mum who spotted the pack on her morning school run.

The user, who wished to remain anonymous, wrote: "I rang council said they are running everywhere in street, they said they will send people down as that’s a very large infestation, but worse now than last week.

"Absolutely disgusting.

"They ran across us as we passed but it’s mental."

The local said the rats were hanging out behind a chicken shop called Chicks.

Commenters on the post were quick to point out how "filthy" the infestation was.

One wrote: "This should be reported to health and safety. Utterly disgusting"

Another posted: "Something needs to be done about disgusting people dumping waste in the streets.

"The problem will never be solved, all the time waste is dumped there!"

Wandsworth Council has been contacted for comment.
