An unmanned drone analysing earthquake damage in countryside near the city of Ravenna, northeast Italy, made an unexpected discovery — a marijuana plantation hidden in some bushes.

“There was a real marijuana farm in the countryside near Ravenna on abandoned land and hidden by thick vegetation,” the police said in a statement.

Police said they had also found “an accurate system” for irrigation and illumination and seized a total of 182 plants.

The remote-controlled drone was intended “to verify the stability of buildings damaged by the earthquake” in May 2012.
