The Kyoto Prefectural Police are expected to take action against eight of their colleagues for allegedly covering up the case of a man who froze to death while he was in their care in 1997, police sources said Saturday.

The eight include officials, administrators and a former police station chief.

The then head of the Kujo Police Station and other employees are suspected of having forged a document in which officers are said to have helped a drunken man on Jan. 16, 1997. Actually, sources say, the man had been left lying outdoors in the grounds of the police station.

Investigation papers on the eight are to be sent to prosecutors as early as next month.
