Analytical approach The banknotes were analysed by MS/MS for the presence of traces of illicit drugs and a comparison was made between the seized banknotes and banknotes taken from general circulation and analysed by MSA.
Findings The cash within one of the bags was found to be unusually contaminated with diamorphine (heroin), and the cash from the other bag was found to be unusually contaminated with THC (the active constituent of cannabis). Result The two suspects pled guilty to the offences and were sentenced to four years and one year imprisonment. A confiscation order for £60,000 was also made.
