Police arrested four people at the beginning of April involved in the ‘old school’ production of the illicit drug heroin – cooking the drug from handpicked, dried and ground poppy plants at a house in Kolín, east of Prague. According to the police, the main coordinator in production and distribution is 43-year-old Jan Jukl, the guitarist for punk band Plexis, together with his girlfriend. News website idnes reported that both were themselves users. The production of heroin in the Czech Republic is rare; according to idnes, 95 percent of the drug comes from abroad - Afghanistan, Pakistan, and other countries in Asia. The gang also produced and sold marijuana and sold the Czech methamphetamine pervetin, bought from a third party.
