Hong Kong police arrested a 26-year-old man in Kowloon’s Sham Shui Po area on Monday on suspicion of possession of an offensive weapon.

At 4pm, the suspect, an ethnic Vietnamese holding a Hong Kong identity card, had an argument with a few other men on Tung Chau Street in Sham Shui Po, Oriental Daily reported.

The suspect allegedly lost his temper and produced a knife, then threatened the men before they all ran away.

Officers of the emergency unit of the West Kowloon Police Headquarters patrolled the area and allegedly found the suspect holding a knife on a street.

Police say they told the man to drop his knife but he ignored them. More officers, equipped with helmets and shields, were then deployed to the scene and subdued the suspect.

The suspect refused to disclose the reason for the argument with the other men, only claiming that he had brought the knife with him to the scene for self-defense.

Officers of the criminal investigation team of Sham Shui Po Police District are following up the case and investigating the background of the suspect.
