Arrests are often viewed as a key measure of law enforcement's effectiveness in addressing crime. However, law enforcement practices with regard to arrests can differ significantly from country to country. In addition to identifying law enforcement's involvement in a particular incident, PSI has been collecting information concerning arrests as an indicator of governments' commitment to address pharmaceutical crime.
Through member and open source reports, PSI documented the arrest of 1,375 persons involved in counterfeiting, diversion or theft of pharmaceutical drugs worldwide during CY 2015. This represented a decrease of eight percent (-8%) from the global arrests in CY 2014.
