Undated photo supplied by Spanish police on July 3, 2009, shows climbing and other material, police say was to be sent by a remote-control four-metre-long zeppelin into the prison in Las Palmas to free an Italian drug trafficker. Accomplices planned to send "Giulio B", 51, the material which would allow him to climb to the highest point in the prison to access a spot with no surveillance, and to then absail down the prison walls. "Giulio B" was serving time for carrying 200kg of cocaine in a seaplane from Mauritania to Spain. The three accomplices were arrested, including one who was watching with binoculars, camped 600 metres from the prison in a camouflage tent surrounded with movement sensors.
