In New Zealand people buying old campervans are at risk of serious illness, owing to the trace chemicals used in the illegal manufacture of methamphetamine, otherwise known as meth.
Detective Sergeant Rhys Wilson warned potential campervan buyers that some criminals have used the vans as portable labs in the same way Breaking Bad's fictional Walter White did.
"The poor person that ends up subsequently buying one has obviously no idea of what it's been used for and what sort of contamination is in it," he said.
Sergeant Wilson urged buyers of potentially suspect vans to come forward, and stressed that those sold directly by drug offenders may contain "significant contamination" that can cause heart, breathing and skin problems.
He said that the police either decontaminate or destroy such vans when they find them.
The camper van warning comes as part of a major investigation into the country's meth problem , which have increased nearly three-fold in the years since 2008.
