The student allegedly made the mistake of taking a picture of himself standing among a patch of marijuana plants and using it as his screensaver photo, ANSA reported Tuesday. Then, as luck would have it, he dropped the waist pouch he used to carry the phone and it was picked up by a retiree who turned it over to police.

When the police called him in, the student allegedly broke down and confessed he owned the pot crop, the news agency said. He took the police to the spot where he was growing his illegal crop and was promptly booked.
