The Bright District Subdivision, the investigative staff of the Criminal Investigation Department, also known as Detective Lan, was conducting a routine review. Every day, various police stations receive a lot of reports, and for general cases, the stations can handle them on their own.
However, more serious cases must be decided by the Subdivision.
Especially now, with an extortion case involving more than six hundred thousand, the one implicated is the very famous Lawyer Tang Fangjing from the internet—that if mishandled, could become another hot topic of public opinion.
The evidence at hand was clearly insufficient; there were only some words from Gao Qingwen, so after consideration, Detective Lan decided to proceed with a preliminary inquiry.
A preliminary inquiry is a preliminary investigation for cases that cannot be filed but still have suspicious aspects. It allows for the subpoena of the parties involved as well as other investigative measures.
