Municipal guards and Civil Police officers went to a chácara, a small country property, in Colônia Murici in the rural area of São José dos Pinhais, in the Curitiba metropolitan region, on Thursday 20 January 2011 after anonymous tip-offs.[1] They arrested the owner of the property, Antonio Olinek, 38, in the act.[1] Officers estimated that about 50,000 cannabis plants had been sown among a maize crop on the property, some up to three metres tall.[1] Olinek told officers he had received the seeds from some young people and said he had no intention of selling the product.[1]

The plants were removed on Friday 21 January and held until the decision to burn them.[1] The burning of the roughly 50,000 plants began at about 14:00 on Monday 24 January 2011 in São José dos Pinhais.[1] A truck carried about 1.2 tonnes of the cannabis plants to a company inside the city whose name was withheld for security reasons.[1] Sixteen security officers, among them municipal guards, Civil Police officers and police chiefs, accompanied the incineration.[1]
