Monkey Found on London Bus Highlights Concerns Over New Primate-Licensing Law

On July 17, a Metroline driver stopped route 302 at Kensal Rise after a passenger’s pushchair was blocked by a laundry bag. When the bag was moved, a frightened common marmoset jumped out of a small metal cage hidden inside. The female, nicknamed “Oyster,” was stressed and dehydrated, surviving on a piece of apple. The driver returned the bus to the Willesden depot, secured the animal, and alerted the RSPCA. Chief inspector Clare Dew opened an investigation; a specialist exotics vet cleared the monkey before it was transferred to a primate sanctuary.

In April 2026, the UK introduced the Animal Welfare (Primate Licences) Regulations, requiring private primate keepers to obtain “zoo-level” licences and effectively banning primates as household pets. Authorities estimate 5,000 primates are currently kept as pets in England, with many owners still non-compliant.

Clare Dew called the incident “clearly intentional,” linking it to the new licensing regime and saying the RSPCA will review CCTV to identify who left the monkey on board. She urged owners struggling with licence requirements to seek advice rather than abandon pets.

A Transport for London spokesperson thanked the driver and confirmed Oyster is now safe under RSPCA care.

Alison Cronin, director of Monkey World, noted that abandoned primates existed before the law and are not solely a product of the new regulations.

Chris Lewis of Born Free argued the licensing system falls short of a total ban and, without strong enforcement, could push illegal activity underground, leading to more covert abandonments like the bus incident.

The Oyster case shows a possible unintended consequence of stricter animal-welfare legislation: owners facing costly compliance may discard primates rather than risk prosecution. Repeated incidents could increase emergency rescues, strain RSPCA resources, and highlight gaps in public awareness of the new obligations. Effective monitoring and rapid response are needed to protect exotic animals in urban settings.
