On 25 November 2014 two British tourists aged 20 and 21 died in a hotel room in Amsterdam, the Netherlands, after snorting white heroin that was sold as cocaine by a street dealer. The bodies were found less than a month after another British tourist died in similar circumstances. At least 17 other people have had medical treatment after taking the white heroin. Health authorities in Amsterdam are warning of the dangerous drugs being sold. Large signs were set up at popular tourist locations in the city. An award of €15,000 is offered for tips about the dealer of the drugs. On 20 January 2015 the last warning signs were removed from the city as there had been no further incidents.
