Caught in the Act: Diner's Tip Leads to Arrest of Foreign National with Drugs
An undocumented foreign national in possession of illegal drugs was arrested after a fellow restaurant patron, who overheard him discussing the substances with his companions, reported him to the police.

The Siheung Police Station in Gyeonggi Province announced that they have arrested a Vietnamese man in his 20s, identified as A, on charges including violating the Narcotics Control Act.

Police also apprehended four other Vietnamese nationals, including a person identified as B, on charges of violating the Immigration Control Act.

A is accused of possessing a small amount of ketamine at a Vietnamese restaurant in Jeongwang-dong, Siheung, around 11:50 p.m. yesterday (June 20).

The suspect's activities came to light after a customer at the restaurant reported hearing A and his group discussing drugs.

Police were dispatched to the scene after receiving a 112 emergency call from a witness who stated, "While I was eating, I heard people at the next table talking about using drugs."

After a search lasting approximately three hours, police discovered that A was in possession of a small amount of ketamine and confirmed a positive result through a preliminary drug screening test.

While the four individuals accompanying A were found not to be in possession of or under the influence of drugs, two were confirmed to be residing in the country illegally, and the other two were found to be without their passports, leading to their detention as well.

"We are currently investigating how the suspect obtained the ketamine and whether there were any accomplices," the police stated. "We plan to transfer the other individuals to the immigration office."
