Police in the northern city of Mathura wrote to magistrates to say 581kg of the drugs had gone missing from two storerooms after the consignments were seized from traffickers more than five years ago.Police had delivered samples of the drugs to the court at the beginning of the trial but were mandated to produce the actual cache to bolster their case and obtain a conviction.The prosecution told the court that nearly 700kg of cannabis stored across several police stations in the district were under threat from rats.They also spoke of the inability to deal with the rodents, which they claimed were overwhelming the most secure places inside police stations.Police in neighbouring Bihar state in the same year claimed rats had drunk nearly one million litres of alcohol kept in storerooms in one of the country’s few dry states."
