The vixen was discovered on March 20 in the BR6 area with one ball bearing lodged in her nose and another fatal wound to her middle.
The Fox Project, a registered charity dedicated to the protection and care of red foxes, shared details of the incident on social media, describing the discovery as “devastating”.
This latest case adds to a series of troubling attacks on local wildlife, with recent reports of swans and other animals being targeted in the area using similar methods.
Incidents have been reported in the Greenwich, Thamesmead, and Bexley areas, including Danson Park and Greenwich Ecology Park, as well as Priory Gardens in Orpington.
The Fox Project says it has notified the police rural task force and is calling on the public to raise awareness about the rise in animal cruelty.
A spokesperson for The Fox Project said: “It’s devastating to think that someone could find pleasure in harming a living being.
This incident is not isolated; across the country, wildlife is being targeted by youths who often face little to no consequences for their actions.
“Numerous reports of catapulting wildlife are surfacing, highlighting a disturbing trend that we cannot ignore.”
The charity, which has operated a wildlife hospital since 1993 and treats over 1,400 foxes each year, is urging people to support a petition that aims to ban the public sale and possession of catapults and ammunition.
The petition, which has gathered over 15,000 signatures, calls for legal changes to allow police to take stronger action against individuals carrying such weapons, particularly in areas known for wildlife crime.
In response to the ongoing violence, a protest is set to be held at Priory Gardens on Sunday, April 6 at 1.30pm.
The event is organised by Greenwich Wildlife Network, the event aims to raise awareness of the frequent attacks in the area, which have included injuries to squirrels and a greylag goose.
Leaflets will be distributed and residents encouraged to stay vigilant and report suspicious activity to police.
Campaigners are asking members of the public to sign the petition, contact their MPs, and share information to help combat the increasing violence towards animals.
