Guards have intercepted two carrier pigeons carrying phones to detainees at a prison in Sorocaba, some 100 kilometres from Sao Paolo, a spokeswoman for the state penitentiary system said.
"Penitentiary agents found the pigeons outside the Danilo Pinheiro prison but, fortunately, the birds did not have time to enter the prison building with the material," said Rosana Alberto.
Each pigeon was carrying a small bag containing a mobile phone and charger.
