Colombia's Anti-Narcotics Police Sunday raided small and medium capacity laboratories in the department of Guaviare, each capable of producing about 50 kilos of cocaine weekly, El Espectador reported.
Officials said the purpose was to detain members of Colombia's Revolutionary Armed Forces and disrupt their income.
Police were aided by local sources who said several buildings in the Guaviare jungle were used for cocaine processing.
The 1st and 7th Fronts of the FARC have been identified as the operators of 21 of the laboratories, with the remaining belonging to the Colombian Revolutionary Popular Antiterrorist Army.
The neo-paramilitary antiterrorist army, which is active in much of central Colombia, has about 1,000 members and is one of six groups of former paramilitary fighters now involved in the drug trade.
