Eight police officers in Argentina were fired after they blamed mice for a missing 560kg of impounded marijuana.
The officers argued the weed was "eaten by mice", The Guardian reports, after their bosses noticed more than half a tonne was missing from the police warehouse near Buenos Aires.
The city's former police commissioner, Javier Specia, left the inventory unsigned, which led to the suspicion by his replacement, Emilio Portero, who then reported the missing drugs.
Of the 6000kg-worth of drugs that had been in the warehouse for two years, only 5460kg were accounted for.
Forensic experts have confirmed it was unlikely the drugs were eaten by mice, The Guardian reports.
"Mice wouldn't mistake the drug for food, and that if a large group of mice had eaten it, a lot of corpses would have been found in the warehouse," said Judge Adrián González Charvay, who is leading the case.
An internal police investigation is underway.
