Reports of a deadly snake on the loose in Camden are suspected to be a “hoax”, according to the RSPCA.

The RSPCA has confirmed it is not investigating claims made earlier this month that a venomous black mamba is roaming the borough.

Residents were left terrified after posters appeared warning that Rosie, a “highly venomous” snake, “escaped from her enclosure” on January 5.

The posters advised residents to check under car seats, bed sheets, behind toilets and in washing machines.

However, all phone calls to the emergency contact listed on the poster have been ignored, including calls made by the Ham&High.

A spokesperson for the RSPCA said: “We don’t know, but we suspect it is a hoax. There has been some misreporting. There is nothing for us to investigate.

“Of course, it is hard to be sure and we would welcome any information.”
