Websites which do not prevent the sale of illegal goods are complicit in cyber-crime, a crime chief has said.
Class A drugs, counterfeit cigarettes and stolen passports are among a host of illicit items and services that can be bought through online listing sites.
Clive Grunshaw, the Association of Police and Crime Commissioners’ cyber-crime lead, said tougher laws were needed.
The illegal services were all found on classified ads website Craigslist.
In secret filming I carried out for BBC Inside Out, the availability of illegal goods on the site was laid bare.
I was able to obtain cocaine from a dealer in Derby, which testing found had high purity levels.
