In November 2013:

There have been local reports of a mini helicopter drone dropping 250 grams worth of what is thought to be cocaine onto a Brazilian prison. According to Brazilian news source Globo, the prison, Centro de Detenção Provisória 1 is 60 miles north of São José dos Campos and currently holds 1,605 prisoners.

São Paulo’s secretary of Corrections claims that at 10am on 7th March, the drone dropped the package onto the prison yard. The prisoners are said to have crowded around the parcel making it impossible for prison officers to gain access to the mysterious load until later that day when a search of each individual cell had to be carried out.

Now, May 2014:

A Lithuanian self-made drone detained in Russia’s westernmost Kaliningrad region last week was used for smuggling cigarettes into Russia, Oleg Dzhurayev, the press service chief of the Kaliningrad border department of the Russian Federal Security service, told ITAR-TASS on Wednesday.

A Russian-Lithuanian criminal group used the self-made drone aircraft for illegally smuggling cigarettes across the Lithuanian border into Russia. Dzhurayev said huge boxes with cigarettes had been found inside the drone when the border guards detained the aircraft on Lithuania’s border with Russia. He did not rule out the drone could have been used for other purposes, including unlawful actions in Russia’s territory.
