A MARIJUANA farm has been rumbled by police in Spain after being spotted during coverage of the Vuelta Espana.
A helicopter was covering the cycle race as it entered Igualada in Catalunya when the aerial shot uncovered the plants atop an apartment block.
The suspicious crop caught the eye of viewers who tipped off the Mossos d’Esquadra.
Officers later visited the property to find it vacant.
Police have confirmed the rooftop terrace contained a substantial marijuana farm with some forty plants being removed from the site.
As yet there have not been any arrests in connection with the seizure.
