More than 60 patrol officers of the Hyogo Prefectural Police falsified some 200 investigation documents in the last two years, apparently to enhance their performance ratings, police officials said Wednesday.
Some officers even fabricated reports on incidents that never even took place, the officials said.
About 10 of the falsified documents were officially submitted to prosecutors, who decided against pressing charges, the officials said.
Minor offenses are frequently exempt from indictment, but records of resolved incidents are counted as part of police achievements.
