A 23-year-old university student sought help from the police days before his alleged involvement in an attempted burglary in the city of Mitaka in western Tokyo, law enforcement sources disclosed Wednesday.

Masaki Saen, who is from the city of Kyoto and a senior at a private university, reported threats that he had received after applying for a "dark" part-time job, or yami baito.

Saen reportedly approached Kyoto police with his mother on Oct. 28, two days before the Mitaka incident, expressing fears over his involvement in a job he found on the encrypted messaging app Telegram.
